Hi all,
I want to do a group analysis using subjects that were run in different studies but who have (some of) the same relevant functional contrasts. Is there a way to run something like isxconcat-sess on data from different analysis streams? Or if not, which files do I need to collect and align from each subject in order to run mri_glmfit? What would be the best way to handle this analysis?
Thanks, Terri
Just run isxconcat-sess for each study, then
mri_concat study1/gamma.mgh study2/gamma.mgh --o study1-and-study2-gamma.mgh
then run mri_glmfit on the above output

Hi Doug,
Is gamma.mgh the same as ces.nii.gz? I'm working with data processed with an older version of Freesurfer, not exactly sure which. I have a related question also; the masks and meanfunc images don't seem to be lining up that well after running isxconcat-sess. Would is be possible for me to use cvs normalization on these data before concatenating within each study? I have run the cvs transformations already, but I'm not sure how I would chose which functional data to apply them to, and if I'd need to set up a new filesystem for the normalized data.
Thanks again! Terri

Sorry, yes, I meant ces instead of gamma. It is not set up to use CVS. On my todo list...
