Search for NAMIC Data

Users earch for data available on the BIRN data grid through metadata applied to the data itself. Each data object and collection can be assigned any number of metadata tags. Currently the metadata tags consist of items such as: Modality (DTI, T1, T2, etc.), Institution, etc.

To see an example of metadata on a data file, take a look at the following UCI file: First

• Ensure you aare logged into the Portal
• Then view the contents of that archive
• Then to search for data, click the Query Metadata button

Replication of Data

Currently, the NAMIC data sets are stored in BIRN at:

/home/Projects/NAMIC__0003/Files (physicall located at NCMIR)
/home/Projects/Study5000__0005/Files (physically located at UCI)

For redundancy in case a Birn Rack were to go offline we have replicated the data to the BWH rack in preparation for the Programmer's Week.

This can be seen when using 'Sls -a'

 [jgerk@ncmir-gpop scratch]$ Sls -a UCI07110773.tgz
 jgerk       0 z-ucsd-ncmir-nas1       451315092 2005-02-18-14.00 % /home/Projects/Study5000__0005/Files/Archive/UCI07110773.tgz
 jgerk       1 z-harvard-bwh-nas1      451315092 2005-06-24-17.02 % /home/Projects/Study5000__0005/Files/Archive/UCI07110773.tgz

During regular use it is not important that the file resides in two places, but it should be understood that removing the file will result in removing both copies.

As more data is added to NAMIC we can periodically run the following command to update the BWH resource (provided you have the correct permissions).

 Sbkupsrb -r -S z-harvard-bwh-nas1 Files

Notes

Instructions on creating Data Repository Pages are here.

• Data Access Uses the BIRN Controlled Infrastructure (requires account)

Namic Domain Creation

Please note that users who previously belonged to the external domain have been added to the namic domain. If you use the SRB S-commands, this mandates a change to your .MdasEnv file if you wish for your default directory to be /home/<your_user_name>.namic or if your default directory was previously /home/<your_user_name>.external. Please update your .MdasEnv file to point to your new default directory.
