2008-12-19

Attendees: Ron, Tina, Curt, Nicole, Xiaodong, Katie

  • Update from UNC will be covered when the participants are able to call in later.
  • Jim Miller mentioned a project to make modules take advantage of the EventBroker. It needs to be a new project with Steve and Jim on it. Tina to add this project.
  • Are there gaps in what NA-MIC has produced before the competitive renewal? A priority for the remaining engineering effort is is to stabilize, clean-up, and document NA-MIC functionality already in place. Much new functionality has been added during the last year. Jim will hold a side discussion during the AHM in January to discuss this.
  • NCI Intramural use of NA-MIC tools project:
    • NCI-Frederick is using Slicer and planning to also utilize XNAT for the storage of images from microscopy, small animal, and angiogenesis labs.
    • The ChangeTracker module is interesting for longitudinal studies in small animals.
    • A new segmentation algorithm will be released into Slicer focused on cell wall identification. The algorithm was developed at NCI and is already released as open source. The module should be in slicer by Spring 2009.
  • Project Review: http://wiki.na-mic.org/Wiki/index.php/2009_Winter_Project_Week#Projects
  • The project list has been recently viewed by Tina and most project owners are filling in the needed details. The Wiki pages still need to have additional detail added.
  • No more TCONs this year as the next two Thursdays fall on holidays. The team will gather after the New Year for the AHM in Salt Lake City.

DBP Projects Planning

Attendees: Martin, Cedric, Clement, Jim, Steve, Nicole, Will, Curt, Katie, Mark, Dan, Jeremy


  • MIND team: Jeremy, Mark, Ross, Steve
    • Agenda Items for discussion
      • status of co-registration
      • status of brain extraction
      • status of bias field correction
  • UNC team: Heather, Jim, Martin, Clement
  • JHU team: Gabor, Katie, Allen
  • PNL team held on Monday Nov 3, 3pm ET
    • Attendees: Marek, Polina, Brad, Guido, Jim, Steve, Tracy, Sylvain, Tina
    • Q to dbp team: what are good alternatives to compare with, and what is a good way to compare?
    • Q: how best to cover all the projects of DBP beyond the roadmap.
    • Suggestion: increase tutorial time to 1 hour to allow coverage of projects with tutorials that have not been covered in DBP presentations

Call Notes:

  • UNC Visit Dates: December 15th visit for Will, Steve, and Julian
  • AHM Planning: All participants need to start updating the Wiki. Tina wants to remind all the DBPs that they have a timeslot for presentations during the AHM in January. The Wiki pages for projects need to be filled out. There will a presentation that is an overview of NA-MIC before the DBP. This is under discussion on what it will contain. Ross gave a NA-MIC overview at the NCBC meeting which could be a good guideline. There is a new format for the DBP presentations where each team has 10 minutes.
  • Each roadmap project needs to have a tutorial that walks users through reproducable results.
  • There is a contest for tutorials with the possibility of a prize awarded to the best tutorial. The message to NIH should be about generating tools that help users to generate answers and results, not just new algorithms. There is a focus on what are people doing with it.

Specific Questions by the DBPs

  • How should the cortical thickness module be integrated with Slicer? An atlas is needed. Should it be stored on NITRC, on the pub-db on SPL, or where? NITRC is attractive because of its download support. The Slicer modules are external modules. The module would be on the Subversion archive on NITRC, the atlases would be additional files (not in SVN). Discussion of how to make the module and the users aware of the atlases.
  • Discussion on Slicer integration: The Cortical Thickness Module is currently a single external module, which calls external application with a separate GUI. These applications call other applications during processing. There are five different modules. For this AHM, users will have to download all required modules, but we should look at how to bundle them together later (via dependencies) or create the concept of a package of modules. Details of how to organize the modules and store them in NITRC was discussed.
  • Tutorial Datasets and Tutorial document should be placed on NITRC next to the module. Add a link to the Slicer Tutorial page referencing the NITRC page.
  • BatchMake is used by Slicer modules. How to create the BatchMake .bmm files so that the modules will initialize the BatchMake config files. This is solved by the two-step Slicer initialization process. The environment variables should be queried to find appropriate paths.

2008-10-30

Agenda:

Attendees: Jim, Will, Tina, Steve, Ross, Marcel (for Guido), Allen, Martin, Nicole, Katie, Dan Marcus, Vince

    • Ross will circulate his talk to the group and solicit input+updated materials (an earlier version was presented in AUgust to all NCBC mtg)
    • Include training and dissemination slides (a couple) into the same talk, and a couple of slides on the NA-MIC Kit
    • Next week will be DBP specific talks: Monday 3pm ET PNL DBP, and Thursday 3pm ET JHU, UNC, MIND

2008-10-23

Attendees: Jim, Chris, Brad, Katie, Tina, Vidya, Noby, Vince, Dingang, Kevin, Ziv, Dan Marcus

External Collaborators:

Highlights:

  • Dingang w/ Jim: two types of software development. MR-image registration algorithm will be extended and added to NA-MIC Kit. Second is for white matter lesion segmentation in MR images. Kickoff mtg will take place within team before January to identify which infrastructure changes need to be made to ITK and Slicer. This will get coordinated with visit to Martin. Team will also look at synergy with Lupus DBP.
  • Chris: EM segmenter is working well. At project week, would like to make it an all-slicer workflow. Dan Marcus will help before project week to get data into xnat central server (data is public).
  • Ziv: work has been divided into IGT Project Week (Dec 8-12) and NA-MIC Project week. The goal is to get a workflow prototyped in Slicer.
  • Vince: meshing is more than likely to be integrated by the time of the project week.

2008-10-16

  • Q for Kitware: VIsualStudio bug in ITKLandmarkTransformInitializer (in the RegisterImages module)
  • Wendy working on XNAT UI
  • Who's going to claim the .xcat extension? Let's have the Wiki specify the correct MIME-TYPE for xcat files, so that at least the file is downloaded automatically, and let the user which application to use (note that Slicer3 should open a .xcat file on the desktop).

2008-10-02

Agenda:

2008-09-25

Attendees: Xiaodong, Katie, Steve, Tina, Curt, Ron

Agenda:

  • Unstructured Grid support to be added to Slicer trunk soon - vtkUnstructuredGrid datatypes are a subtype of slicer models. There will be some changes to the slicer model viewers and hierarchy viewers to allow display and control over these datatypes. This was put in to support the finite element meshing module to be incorporated in Slicer in advance of the January 2008 All-hands meeting.
  • Meshing Module into Slicer - Curtis is working on integration of the standalone Univ. of Iowa meshing application as a Slicer module. Integration is working through MRML but the GUI is not integrated in Slicer's window yet. Sebastien has offered debugging help. Curt will be delivering a code sample to Sebastien during the next week for assistance in KWWindows integration.
  • GPGPU RayCasting - There is an open-source ray casting algorithm using OpenGL shaders that is experimentally being integrated with Slicer. If this is successful, the algorithm will be integrated into the Volume Rendering module and be available for use by the NA-MIC community.

  • Download modules from NITRC by an end user
    • Where does this stand - Sebastian has committed the code to the Slicer3 tree.
    • Sebastian will be happy to help someone push this forward
    • How to pack modules to have Slicer3 install and find the modules?
    • What infrastructure is needed- particularly for Windows to check for the proper compiler and build type. Possibly have CPack generate keys that check this.
    • Slicer3 should provide the user with a list of modules that can be downloaded and installed.
    • Sebastian will work with Modules to create their own package for installation.

2008-09-12

Attendees: Jim, Sebastien, Tina, Curt, Dan Marcus, Will, Ron, Wendy


Agenda:

  • Curt - Working on the integration of a standalone KWWidgets/VTK application as a loadable Slicer module. This standalone application does lots of callbacks to the RenderWindow and creates its own KWWindow and KWUserInterfacePanel. Therefore, this is a complicated example to integrate into Slicer's Module panel. At the current time, the widget creation seems to occur without warnings, but the panels never show up in Slicer. Sebastian and Wendy indicated that the management of the InterfacePanels and Slicer's UserInterfaceManager is intricate and that there is probably a relatively easy fix, but Sebastian would have to review some of the source code to comment further. Curt will make the source code and screenshots available to Sebastian for a follow up call later.
  • Sebastian - Evaluation of GUI-testing for KWWidgets and QT is ongoing. Sebastian is working on this as well as the requested tree control widget.
  • VTK bugs (Will) There were three VTK bugs reported last week in the TCon. Karthik solved all of the bugs. Kitware has fixed these and the fix is in the VTK CVS head already. The bug information is listed below:
  • Work is beginning on the planning for the All-hands Meeting in January. There will be another party. Ron and Will are working on the agenda already. We should put up the draft projects template soon.
  • XNAT visit followup discussion. The Web Services API is stable and it will be tested as the Slicer use case (written by Wendy) is implemented. There was discussion of the use of Slicer tutorial data to populate the use case. Wendy is developing a Slicer module to query the XNAT Desktop Services. There are is a set of minimal, required tags. The required ones are all that is necessary at first for the use case, unless there are others needed by the Use Case requirements.
  • MICCAI comments - One of the Slicer images received second place in the Visualization competition. There was a Slicer plug-in workshop offered and an IGT workshop given at MICCAI. Vince was helpful in making the Slicer tutorial possible.

2008-09-04

Attendees: Dan, Xiaodong, Wendy, Vincent, Curtis, Nicole, Tina

  • VTK Bugs in 5.2 - These are issues with the integration of the meshing tools
    • 0007518 - vtkDataReader Memory Errors causes a seg fault
    • 0007511 - Bug in vtkSmoothPolyDataFilter causes a seg fault
    • 0007512 - vtkPlaneWidget Sphere Resizing - This is simply an annoyance
  • Slicer/XNAT update
    • Reading multiple files from a single data needed in Slicer
    • Building out the UI and workflow for talking to XNAT
    • Expected to have prototype Slicer/XNAT File Repository integration by October
    • Expected to have prototype Slicer/XNAT Enterprise integration by January, 2009
  • Sadness all around at the lack of a Kitware representative to disucss VTK bugs
  • Great joy at being set free after only 20 minutes

2008-08-28

  • Plan for XNAT/Slicer interaction: 9: Sebastien, Katie, Wendy, Nicole, Jim, Vince, Steve, Curt, Dan
  • XNAT Desktop, Web Services Use cases (Wendy review of last weeks meeting notes)
    • Web services file repository api is currently on XND, but will also be supported on XNAT Enterprise (by January).
    • Sebastien and Yumin are working on the current save dialog box and will think about how the remote repository should look for that.
    • discussion of how extra data file names are handled in ITK (which files are actually written when you save a particular archetype).
      • idea: save to temp dir to get file names. Rather than changing all ITK io factory code to keep track of which files it wrote, the slicer code can keep track of what files are in the save directory before and after the Write method executes (this assumes that each factory will only save files in the single directory, but that seems like a valid assumption for all known code).
    • discussion of refining upload uri also how to keep track of metadata to store with derived data
      • how much can be kept track of automatically in mrml? Maybe a lot...

2008-08-21

Attendees: Xiaodong, Steve, Curt, Ron, Nicole, Marco, Katie

  • Update from Marco on BatchMake coordination with GWE
    • Plan is to wrap GWE for use with BatchMake and Julien is working on it
    • Waiting for Kilian's updates for scripts
    • Ron says we need users to be actively using tools so we have a clear story for renewal - Marco to look at the NA-MIC DBP projects and see which are good fits with GWE and Ron can help facilitate connection

2008-07-17

attendees: jim, nicole, wendy, katie, dan, xiaodong

Notes:

  • Wendy has nearly fixed the packing issue introduced with the Compare View.
  • Xiaodong has added capabilities to vtkITKArchetype..Reader to identify "sub-series". This is necessary for time series data where the all the timepoints are stored in one series. Steve to build a UI to select sub-series or load them all. Perhaps XNAT desktop can help in storing meta data of registered data for fast browsing.
  • Selecting models and volumes for manipulation. Can we tie "active viewers" to the module panel (so the modules show information from the "background" volume, etc.)?
  • Release date? Before NCBC meeting?
  • Jim is off the grid the next week :)

2008-03-27

Attendees: Steve, Will, Xiaodong, Nathan, Katie, Wendy, Tina, Nicole, Marco, Sebastien

  • Nathan will discuss presentation of fluid mechanics projects.
  • Update from Core 1 + Core 2 meetings in Utah earlier this week.
  • Discussion of Module Chaining (Marco and All)
    • Requested by Core 1 to systematize common use case
    • Need several steps in an analysis process to act like a single command
    • Would like something akin to the EMSegment workflow wizard, but as command line module rather than built-in module

Highlights:

Nathan's overview: discussing visualization options for his fluid velocity vector fields for tractography algorithm. Steve mentions a few options:

  • A LDDMM module in Slicer2 that does animated vector field visualization (work done in collaboration with Johns Hopkins: Anthony Kolasny, Mike Miller, et al.).
  • Another option would be to try using ParaView as a way to flesh out specifics, and then build a more custom tool for tractography later. Will will point Nathan to documentation for file formats, data formats, etc. or help with any questions, and Nathan will try this out.

Discussion of these topics at the engineering review in Utah:

  • chaining modules together
  • grid wizard (Marco) for grid and batch computing
  • Bspline registration
  • setting up repositories for collecting slicer modules (as technology transition mechanism)
  • how this will fit into the slicer build process
  • diffusion weighted imaging, shape analysis, and segmentation
  • dicom to nrrd converter...

Milestones were set for April-end, Project week, and AHM.

Module chaining discussion (see link above):

  • Java version as first goal -- eventually C++ implementation.
  • Discussion about module discovery process and how will chained modules be packaged: (c++ stub programs? or

or discovery find chain-descriptor xml files? shell scripts? (cross-platform issues)...)

  • Goal: By project week in June we would like to be able to chain modules developed by Core 1.

Sebastien's update on module building: Wiki will be updated today with status. (link)

2008-03-20

Attendees: Tina, Jim, Will, Wendy, Xiaodong, Nathan, Martin, Marco

  • Progress Report - read over the assignments. We will look for progress from June 1, 2007 to May 30, 2008.
  • June 23-27 is the summer project week. We will make first pass on projects in late April.
  • Module discussion: Martin wanted to understand the state of module creation and usage within Slicer. Sebastien is working on modules that are built against an installed module. Terry is working on built-in modules for Slicer. Jim is working on modules using CMake in the NTRIC repository.
  • Nathan- write a command line, Slicer module that is a wrapper to a web service. Nathan thinks he can get this done prior to the June AHM. We referred to Jim's presentation at the Utah SLC Core 1/Core 2 meeting.
  • We will talk about grid wizard next week at SLC

2008-03-06

Attendees: Steve, Jim, Katie, Nicole, Tina, Xiaodong, Marco, Ron

Highlights:

2008-02-28

  • Attendees: Jim, Steve, Wendy, Katie, Tina, Jeff, and Marco (Grid Wizard Guy)
  • Discussion on time series analysis (viewer, scene markup). Initial viewer will be a general tool for comparing images.
  • Avalanche of new features in grid wizard and GSlicer3
    • Proxy around Command Line Modules
    • Extends command line with specifications for ranges of values as well as specify remote resources (data) that need to be transferred to/from the grid.
    • Uses Velocity for parameter template engine
    • Grid selection and authentication still being refined for Slicer
    • Could be extended to other grid types (LSF, etc.)
    • Lots of information on the website. Instructions for installation. A bit daunting for non-grid people. Some of us will have to work through the instructions step by step to evaluate.

2008-02-21

  • Attendees: Xiaodong, Jim, Katie, Nicole, Will, Steve, Nathan, Tina, Ron, Padma, Marco

- Nathan brought us up to date on fluid mechanics tractography

- Padma Sundaram: SCIrun environment supports EEG processing

- Marco is releasing Grid Wizard alpha version

- Nathan brought up the helical digital phantom web service. Currently the thinking is that it can be accessed through a web service. We suggested that Nathan write a wrapper, consistent with Slicer's execution module, to invoke the web service. However, since it is not available in source form, NAMIC cannot accept it as part of the NAMIC Kit proper. We can guide Nathan in the execution of this module.

  • Attendees: Xiaodong, Katie, Will, Sebastien, Steve, Mike, Wendy, Haiyi, Dan, Curt, Tina

Other NA-MIC Projects

16 - CPack (Katie): Slicer3 compiles and packs using the new C-tools with some bug fixes. Using CMake to select desired modules, using something similar to cygwin. Official Slicer3 snapshot tagged. Different Tcl/Tk versions are currently used for different platform. This need to be addressed.

17 - Slicer GUI Style Guide and Cookbook {Wendy}: This will be a long term effort. During the programming week, the design and implementation details were discussed. The Cookbook will be launched from Slicer, act like KWWidget tour.

18 - Volume rendering (Steve): UI is fairly stable.

19 - Volume rendering using Cuda (Steve):

20 - 3D W Widgets and Picking (Will): found a list of candidates of widgets for Slicer. A few bug fixes for VTK.

21 - XNAT Integration (Dan): Requirements were gathered for a XNAT application that organizes files and caches files from XNAT repositories. Some XML format issues have been addressed.

22 - KWWidgets Roadmap (Sebastien): Gathered requirements. Been working down the list of the feature requirements.

External Collaboration

1 - Astronomical coordinate system support [Harvard IIC] (Mike): Astronomical datasets are quite different from medical dataset. Wendy helped with re-centering data. Made progress in converting between coordinate systems (Cartesian to Spherical).

2 - New Meshing Techniques into NA-MIC [Univ. of Iowa]

3 - Meshing Workflow into Slicer [Univ. of Iowa] (Curt): Will be integrated into Slicer soon. Command line program using VTK.

2008-02-07

  • Attendees: Ron, Will, Steve, Wendy, Nicole, David G, Mark S., Casey, Sebastien, Curt, Luca

DBPs

1 - Stochastic Tractography in Schizophrenia (need to be invited to follow-up TCon)

2 - Cortical thickness analysis - testing EM segmenter to their data. They estimated parameters and tested during the week. The goal now is to compare ITK-MS and EM segment module to see how these two tools compare for cortical thickness. They are reviewing the tools using the same patient data.

3 - (Mark Scully) Legion segmentation using EM segmenter and other options - worked with Brad using 2 channels of data. Flare as 3rd channel caused problems. Desired to have T1/T2/Flair together as three channel dataset. Marcel is going to deliver his segmentation algorithm software to them to compare results.

4 - Robotic Prostate Interventions - (David Gobbi) Working on transrectal biopsy module for Slicer. They had a previous module for transcranial biopsies. One of the most exciting developments was a new prototol "open IGT-Link" which will replace navitrack inside Slicer. Image transfer is working over this protocol. A simulator is being developed for the robot. A few VTK bugs may have been discovered during this process, but it isn't on the top priority list right now.

5 - Prostate Cancer - Wrote new ITK filter that has been submitted to the Sandbox. They are looking at spherical wavelets for shape segmentation. The wiki page will be updated soon.

Other NA-MIC Projects

1 - Groupwise Registration - (Casey) New Bspline registration method is being developed here. It has been used for another project by Casey (#6). Page needs to be updated.

2 - (Need to be invited to follow-up TCon)

3 - (Need to be invited to follow-up TCon))

4 - (Need to be invited to follow-up TCon). Page needs to be updated

5 - Incorporating DTI tools into NAMIC toolkit - They are gathering a dataset that has both structural and DTI data in agreement. Previous dataset was missing part of cortex. UNCDB2 dataset has full coverage of the brain. Resolution is a bit lower, but full coverage is an advantage. Page is close to up to data. Just submitted a paper to ISBI 2008 and working on MICCAI paper, as well.

  • NITRIC is g-forge and would be a good place for automated build process for Slicer modules. This could make it easier to configure Slicer in client labs without need to build from source. This is still being developed by the NA-MIC core team. There is an entry on the collaboration section of the NA-MIC website. Also www.slicer.org/Documentation link.

6 - (Casey) Worked with Serdar using groupwise registration tool. They are currently evaluating results of this study. More images will be added.

7 - (John Melanakos) Spent last week working with collaborators on the MICCAI paper. Project page is well filled.

8 - (Need to be invited to follow-up TCon)

9 - (Need to be invited to follow-up TCon)

10 - MRML scenes for execution model. Some of the issues Brad was having have been resolved. Alex is making adjustments to MRML library as needed for the EM segmentation model.

11 - (Curt) Unstructured Grids in Slicer - Finite Element modeling process was originally in a standalone VTK application. The first Slicer module integration did not use MRML based storage. We are now creating subclasses of Model and Unstructured grid data for storage and display in Slicer. Some minor issues need to be worked out, but the MRML extensions for UnstructuredGrid datatypes are working.

12 - Python (Luca) MatPlotLib plots are close to happening within Slicer. Steve believes it is 80% complete. Python command line modules are working now. Multiple arguments had to be worked by Luca. He has developed Python-based CLI modules. The event broker is discussed here because it affects the interaction with Python, because a Mutex lock has to be placed on the MRML scene. Dan has been helping with metamodules - a single Python module which calls other mothers (hierarchical execution, recipes, etc.).

  • Ron asked about using this scripting technique for the ModelMaker. Some of the parameter setting, etc. could be set in the top module. Nicole will look at this. Kilian said that he wanted to call the "modelmaker" from another module.
  • A need was identified for new wiki pages: (1) scripted modules, (2) metamodules, (2) python scripted modules

13 - (Luca) Transform hardening - Sometimes images are not XYZ alligned. How will command line modules treat an object if it is the child of a transform. The module needs to be able to apply xforms to data (after hierarchy is flattened) to get xformed data. Jim and Steve talked through this lately becomes of the transforms access two-directions (from parents / to parents, etc.) They are looking at how to change the model.

14 - (Steve) MRML support for out-of-core processing - Steve put a link to a new page. Dan, Jim, Wendy, Steve, etc. working through NAC renewal grant (5 years). Multiresolution and asynchronous data are likely targets for this effort, but it will be a long-term effort.

15 - Event Broker discussion - Steve has made process on this, but this wiki page is older. See the event broker page. (look at link under Objective). New term "observation" : completely introspectable. A full dependency between objects is implemented. When a subject issues a "modified" event, Delete events are maintained. Complete "relationship" management of the interaction between objects. This helps by allowing asynchronous event processing. MRML has been converted to use the event broker with asynchronous events managed by the Slicer GUI (async events invoked after GUI events are done). This hasn't broken anything so far, but should improve scalability. Dot logfile format can be generated for inter-object dependencies. This can be used to help provide "who called who" traces. Some special magic is done in MRML Display nodes. They set "observation nodes"
