Hi Anson

you can create them in tksurfer easily enough if they are cortical.

Hi everyone,

I am attempting to create and ROI and look at cortical thickness only within this region (ignoring results outside this region in hopes of saving some time going through and re-assiging voxels with poor segmentation).

Question:

How should I create the ROI (typically I would use MARSBAR, but I don?t think I quite understand the space relationship between MNI-normal and ?FS? space, so what would be the easiest way to make compatiable ROIs and apply them to my group data if I am starting with un-processed T1. Images (recon-all everyone, then quality check only the ROI?)

Thanks a lot!

Anson
