If the source is the FSL standard brain, then use
$FREESURFER_HOME/average/mni152.register.dat as the registration. See if
that works at stage 4.

Doug, thanks
So, is this a correct sequence:
Im extracting thickness measures from VBM contrasts generated by FSL VBM
analysis (this is 2X2X2):
1. To convert VBM contrast file to a binary mask:
mri_binarize --i vbmcontrast.nii.gz --o vbmmask.nii --min 0.95 --max 1 (for
fsl vbm generated corrp
You'll have to sample that mask onto the surface using mri_vol2surf with
the --interp nearest option. You will also have to have a registration
matrix, which will depend on where the volume came from.

I have a mask file which I need to overlay on the individual images of a
group of subjects to extract thickness values within ht mask. But the mask
is of dimension 2X2X2, will this be an issue?
Thanks
