Hi all: I'm performing the group analysis on my own data using command line on FS5.1.0 and i'm a little confused about the Clusterwise Correction for Multiple Comparisions. the command is as follows: mri_glmfit-sim \ --glmdir lh.gender_age.glmdir \ --sim mc-

Re: [Freesurfer] Crippled fiber tracts in healthy subjects (TRACULA)

Hi Ansgar - From looking at your data, the reconstruction of the ccg failed b/c it goes erroneously into an area superior of the cingulum. You can see this clearly by looking at the slice view of the cingulum in freeview (the isosurfaces in the 3D view don't always tell the whole story). It's pos

Re: [Freesurfer] TRACULA: isn't the posterior distribution a probability?
