Hi FS experts,

I have run my analysis using the dev version and have all the necessary volume.txt files. As a secondary step, I want to use some of the subfields as seed volumes for tractography (using ExploreDTI). I have may diffusion data in the same space as the FS brain.mgz but am wondering how I should make the subfield masks so that they will be in the same coordinate space when exported as a nii file. If I use Freeview and load the brain.mgz and then the subfield volumes, is it simply a case of reducing the LUT to the specific subfield and then save that as a volume/mask ? Will that mask be in the same coordinate space and regsitered the brain.nii too.

Is it just a matter of doing this process numerous times in Freeview and each time simply changing the LUT corresponding to the specific ROI needed to get the masks I want to use for each subject.

Thanks for any information you can offer

Best regards

Erik
