Hi Team, Currently I'm working on ROI analyses. I saw one article related to VolumeROICorticalThickness in Free surfer wiki. Could anyone please tell me what is the anatomical file(TT_avg152T1.nii) they are referring to? I took AAL ROIs from SPM.

Hi Doug, I am able to run mri_segstats with slabel below, but it is finding two segmentations in my label and producing a column for each. one is associated with an ID of 0 and one is associated with an ID of 1. I assume that I want the 2nd column (the ID of 1). What is the command doing? Is it

Hi Doug, Thanks for the response. Regarding #1, I am still confused. if the ROI boundaries computed in native space are mapped to fsaverage/mni305 space, doesn't that mean the actual computing of the averages is done in fsaverage/mni305 space? Why would mapping to fsaverage/mni305 space be ne

Hi Freesurfers, I have some questions about ROI analyses. 1. I use the mni305 and fsaverage flags during preprocessing. Does this mean that when I run funcroi-config, funcroi-sess, etc, the analysis is being done for each subject in mni305 space, as opposed to native space? Meaning, If I spec
