Hi Scott - great to see someone trying out one of the sexy new features!
It sounds as if the timeseries stats wasn't happy - could you tar up the
FEAT output directory and your custom FLOBS directory and compress it and
stick it on a web/ftp server - we'll have a look.

Other processes (MC, Melodic, and Registration) appear to have worked correctly. When I use the default FLOBS hrfbasisfns.txt file, thresholded activation maps are generated. I've changed the permissions on the hrfbasisfns.txt file so that they match those of the default FLOBS file (default had a+rw, the hrfbasisfn.txt I generated had a+r), and

However, after changing the output format to ANALYZE in fsl.csh,and processing the data again, I received the same error message (and again, everything worked well when the default FLOBS hrfbasisfns.txt was specified). In addition, the output files in the stats directory appear to be in nifti format (e.g., pe15.nii.gz)?
