Ok now I faced another problem saying that I dont have talairach.xfm for monkeys. Would you tell me how can I generate it for monkeys? Shahin Nasr

It is needed in make_average_surface. I've created a new version that does not use the aparc (thought I have not tested it). You can get it from here:
ftp://surfer.nmr.mgh.harvard.edu/transfer/outgoing/flat/greve/make_average_surface.no-aparc
Make a backup of your current version of make_average_surface and then copy this one over it

Yes, I have made a template on the basis of many monkeys (mris_make_template) and then I have done spherical registeration for each individual monkey (to this template) by using mris_register. Now it is the final step and I have to run the make_average_subject but it generates an error saying that I don't have a lh and rh.aparc.annot files. Apparently very old versions of freesurfer (version 3) didnt need these files. Am I right? Do you suggest to use old versions? Shahin Nasr

Hi Shahin
have you run spherical registration? If so, to what target? I don't think the monkey-to-human atlas aligment is that robust, so you would need a monkey geometry atlas (which is a lot easier to build as you don't need to do manual labeling for it). Probably someone on list has one?

Thanks Bruce,
To avoid this problem, is there anyway to run
make_average_subject without
having lh and rh.aparc.annot files? Shahin Nasr

Hi Shahin
you'll need a monkey atlas based on manually labeled monkey folding patterns. we don't have one, but it's possible that someone else on the list does (it would be a lot easier to do for monkey than it was for
human
as the folds are so much simpler)

Hi Freesurfers,
Anybody knows how can I make lh and rh.annotation.aparc files
for a monkey?
I need them initiate an brain averaging process. Shahin Nasr
