Nope. Try using fslregister with --dof 12 and use $FSLDIR/data/standard/MNI152_T1_2mm_brain.nii.gz as the --mov. doug Yigal Agam wrote: > Thanks, Doug. Also, how can this be done from an individual brain to > mni152? Do I need to use fsaverage as an intermediate? > > Yigal > > Douglas N Greve w

2009-10-23 Thread Douglas N Greve
It depends on a couple of things. If you don't have any continuous covariates, then the difference will be in the computation of the noise and the DOF. With all groups, you'll be computing the noise variance across all subjects, and you'll have a much higher DOF. The size of the difference betw

Hi - Thanks for your help. I have 3 groups and am trying to run an ANOVA and series of t-tests. First, I ran mri_glmfit with two rows in my .mat file (1 -1 0, 1 0 -1) for the ANOVA. Then, before I ran into this webpage https://surfer.nmr.mgh.harvard.edu/fswiki/FsgdExamples, to do a follow up

Hello FS experts, I have a large number of subjects to go through with running FS and I was wondering if there is any other way that I can speed this process up? Where I work, they have a "super computer" system where they can run parallel processing and I was wondering if Fs is able to run on
