Back to Harvard DBP 1
In order to handle the data,
- You need IRB training (human subjects protection) and we need your proof--most PIs have taken the training and provided copy of the certificate (as a pre-requisite for the grant)--others handling data should do the same.
- Don't give the data to other people. If somebody wants the data, they should go and talk to Sylvain Bouix who will check if the data can be shared.
More guidelines will be discussed during the AHM next week.
Keep in mind that IRB training and certificates are mandatory and access to data is restricted to those with IRB approval.
- Note IRB must be updated annually in some institutions.
The description of the data can be found here.
- 2/2005: The legacy data has been converted to one single file format, nrrd, which contains information that we think is necessary for handling medical data. We will provide the NAMIC community documentation for the file format at the NAMIC meeting for both the medical and computer oriented public. We have a total of 188 morphological cases and 80 diffusion cases. The cases have a unique BIRN identifier. Information about diagnosis, data parameters and labels associated with Region of Interests (ROI) are on the BIRN site in the following Excel files:
- morph-NAMIC.xls : Gives diagnosis, age, gender as well as the ROIs drawn for each morphological case.
- morph-ROI-description.xls: Gives for each ROI set, the label corresponding to specific structures.
- diffusion-NAMIC.xls: Gives diagnosis, age, gender, ROIs drawn and when existing, the corresonding morphological data ID number.
- diffusion-ROI-description.xls: Gives or each ROI set, the label corresponding to specific structures.
- 1/2005: After discussion with Steve Pieper and Gordon Kindlman we are leaning towards the NIFTI-1 or nrrd format. NIFTI-1 has more info about orientation but is a bit cumbersome for multidimensional data (e.g. tensor). Nrrd lacks information about the world coordinate system. NOTE: orientation information has been added to NRRD, and to the "unu make" command-line tool that is the most convenient way to generate nrrd headers for a given raw datafile, so that now NRRD can losslessly encode all the orientation information found in the in the NIFTI-1 format.
- 12/2004: We are finalizing the collection of complete data sets. Formats vary across different data sets, genesis, signa, dicom, mrml... We need a single file format able that is simple and can handle orientation properly (i.e. not Analyze).
