Hi Sheeva,
With stxgrinder-sess, t-test is not saved when contrast is "omnibus", probably because omnibus contrast is "all tasks vs. fixation" and t-test would be irrelevant.

Hello,
I am trying to create and view an omnibus contrast for one subject. When I type the appropriate command:
paint-sess -analysis SNgamma -contrast omnibus -space sph -spacedir sphsm20 -d . -s sub28a -subject sub28_recon
I get the following error:
paint-sess logfile is /autofs/space/perun_004/users/sheeva/fMRIanal/log/paint-sess.log
setenv SUBJECTS_DIR /space/perun/3/users/cylix/Subjects INFO: painting onto white grep: /autofs/space/perun_004/users/sheeva/fMRIanal/sub28a/session.info: No such file or directory SpaceDir is sphsm20 SpaceSubDir is sphsm20 INFO: setting srcsubject to ico ------ lh hemisphere ------ Thu Mar 8 13:12:00 EST 2007 SpaceDir is sphsm20 INFO: Painting onto sub28_recon ERROR: cannot find any files with /autofs/space/perun_004/users/sheeva/fMRIanal/sub28a/bold_SN/SNgamma/sphsm20/omnibus/sig-lh
It seems that stxgrinder-sess created fsig, f, iminsig, and minsig files, but did not create t or sig files. This only occurred for the omnibus -- it didn't happen with the other contrasts. I don't know if I should be doing something differently for the omnibus as compared to the other contrasts -- any insight would be greatly appreciated.
Thank you! Sheeva Azma
