UXP & functionality planning for Slicer's XNE client
Workflow & Implementation approaches
All Workflow Steps:
- Select XNAT Enterprise server
- Authentication dialog presented
- Dialog input is processed
- XNAT queried for projects
- response is checked for http error codes
- xml parsed to get list of projects
- GUI populated
- One project selected
- XNAT queried for subjects in that project
- response is checked for http error codes
- xml parsed to get list of subjects
- GUI populated
- One subject and filters selected to narrow search
- User selects "search" for all scans
- XNAT queried for appropriate scans
- response is checked for http error codes
- xml is parsed to get list of scans
- GUI is populated
- User selects one scan and "download"
- Scan is loaded into Slicer
Each step is detailed below.
1. Select XNAT Enterprise Server
2. Authentication Dialog Presented
- Enter user name and password
3. Process Dialog Input
- Save the username (XNE_UserName) and password (XNE_Password)
- Authenticate and create a session:
curl -d POST $XNE_Svr/REST/JSESSION -u $XNE_UserName:$XNE_Password
4. Query XNAT for Projects Available to User
- XNAT queried for appropriate projects
curl $XNE_Srv/REST/projects?format=xml --cookie JSESSIONID=$sessionID
- response is checked for http error codes
- if error is found, report to user
- else xml is parsed to get list of scans
5. User Selects One Project
6. Query XNAT for Subjects in Selected Project
- XNAT queried for appropriate subjects
curl $XNE_Svr/REST/projects/$projectID/subjects?format=xml --cookie JSESSIONID=$sessionID
- response is checked for http error codes
- if error is found, report to user
- else xml is parsed to get list of scans
7. User Selects One Subject
8. User Selects Pull-Down Filters to Narrow Search for Scans & Selects Search
* Experiments: { Experiment_IDs }
** Imaging Sessions: { MR, PET, CT ...}
*** Scans: { Scan_IDs }
*** Reconstructions: { Reconstruction_IDs }
*** Assessors: { Assessor_IDs }
** Non-imaging Assessments: { Asessor_IDs }
Default selections?: All Scans
8. Example Query XNAT for All Scans for Selected Experiment
- XNAT queried for appropriate scans
curl $XNE_Svr/REST/projects/$ProjectID/subjects/$SubjectID/experiments/$ExpID/scans?format=xml --cookie JSESSION=$sessionID
- response is checked for http error codes
- if error is found, report to user
- else xml is parsed to get list of scans
