Re: [Freesurfer] Diffusion Tutorial and GroupAnalysis.csh

Hi Antonella,

1. On the FS Diffusion Tutorial webpage I found for the Group Analysis the following scrip: GroupAnalysis.csh with the following instruction:

# Assemble input for group analysis set type = CVS-to-avg35 # alternatively could be 'TAL-to-avg35' or 'MNI-to-avg35' Can you please explain what means TAL-to-avg35 if my DTI data (FA) is by default registered on the TAL space and I got the file fa-tal.nii? How I can get the TAL-to-avg35 template? Is this different than the one on which my data was registered by default?

There is probably a typo in the tutorial. It should read # alternatively could be 'TAL' or 'MNI'

You can replace the mri_cvs_registered files with any other tools output that you want to use for your final comparison.

3. Can I load my FA group data registered on TAL: group-fa-tal.nii with tkmedit?

Yes, you shoud and also with Freeview.
