Data from the course

All data can be stored on on BLiSS (lts.cla.umn.edu), in /pkg/classes/psy5065/Data. Each day's data are stored there in its original format -- a "study" directory for each "subject," which contains a different DICOM directory for each scan. In most of the study directories, some of the DICOM data have been converted to Nifti format. Nifti files from a few days will be moved to topical directories (DistortionCompensation and DTI), to demonstrate pre-processing or analysis steps.

A brief guide to converting and viewing (and analyzing ... although that section is very brief) is provided here . Don't hesitate to contact the TA if you want help moving, copying, converting or analyzing the data.
