The registration file maps between the FS anatomical in "conformed"
space and the label volume. If they are the same voxel-for-voxel space,
then use --regheader, otherwise use bbregister to get the registration
file and pass that to vol2surf

Hi Bruce,
Thanks for the reply. I am not sure if I am fundamentally wrong at
some places. I am new to freesurfer, previously I processed some .nii
files with recon-all command which created surfaces like
lh.pial/rh.pial etc. After that I did cortical percellation. But the
data that I am using now are IBSR
(http://www.nitrc.org/projects/ibsr) manually labeled volume data
(contains img/hdr/mat file). But I want to get labeled surface like
lh.pial/rh.pial from this labeled volume data. I was looking into
mri_vol2surf command, but it needs a parameter --srcreg which I am not
sure about. How can I get this registration file? Do I need to create
this using freesurfer?
I highly appreciate your time and suggestion.
Thanks

If the labels are a segmentation volume, then you'll need to run
mri_vol2surf with --interp nearest.

Hi Razib
yes, I think mri_label2label will do this if you have
reconstructed the surfaces.
cheers

Hi,
I am wondering is there a way in freesurfer to map manually
labeled IBSR MRI
.img/.hdr volume files to freesurfer surface file (e.g.
lh.pial/rh.pial
etc.) keeping the original labels?
Thanks,
Razib
