Hello Freesurfers,
We are doing functional connectivity analyses (http://surfer.nmr.mgh.harvard.edu/fswiki/FsFastFunctionalConnectivityWalkthr...). We are on the group analysis step of step 8.
On our data set, we ran the following glmfit command:
mri_glmfit --y ./mgh/v.amy.mgh --fsgd ./FSGD/staibase28.fsgd doss --mask ./masks/gm_mask.mgz --C baseline.mtx --glmdir ./glmdir/v.staiamybaseline28.glmdir
Then we corrected using this command:
mri_glmfit-sim --glmdir ./glmdir/v.staiamybaseline28.glmdir --sim mc-z 10000 2 mc-z.absolute --sim-sign abs --cwpvalthresh 0.99 --overwrite
However, when we looked at the results, the mc-z.absolute.sig.cluster.summary, mc-z.absolute.sig.cluster.mgh, and mc-z.absolute.sig.ocn.mgh files were all different. Which of these should match the .summary file? Should they all differ? Is the summary file the final corrected results we should report? If so, what does it mean that the other files do not match?
We viewed the latter two files in tkmedit using the following command:
tkmedit fsaverage orig.mgz -aparc+aseg -overlay ./glmdir/v.staiamybaseline28.glmdir/baseline/mc-z.absolute.sig.cluster.mgh -fminmax 1.3 3
Thanks for the help!
Best, Omar
