Dear All,

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?

2) I was trying to find an explanation for the color map: Min, Mid, Max and Offset values in Free View. Can someone please explain me if I have the color map set it up as HEAT what is the meaning of the above values if for example I am viewing the existing clusters after multiple comparison for the DTI data.

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

Many thanks.

Antonella
