Hi Alain

I believe if you specify the transform as identity.nofile that should do the trick. Most of our tools accept this

Hi everyone,

I've used a couple of ROIs that have been drawn in the mni space for connectivity analysis. Since I have my connectivity results shown on a surface, I want to show the ROIs in the same way.

I have checked with freeview, and the ROIs are correctly placed in the fsaverage/orig.mgz space.

I wanted to use mri_vol2surf in order to reach my aim, however this command require a transformation matrix, and in this particular case I don' really know which one to use, as I don't want to change space. I thought that maybe i could provide an identity matrix, but I don't know what would it be an acceptable format for it.

Have you got any suggestion ?

Alain
