Thanks Bruce for your speedy response.
I am dealing with chimp scans and therefore am trying to avoid anything to do with Talairach. The surfaces have reconstructed pretty nicely using recon-all, but I’d like to create an average surface now.
I will try as you suggest

Sure, I guess you can just run mri_average. I think also if you specify the file name for the transform as identity.nofile to any binary that takes an lta file, the code will internally create an identity transform.
I won’t look pretty though…. Cheers Bruce

External Email - Use Caution Hi there
I’d like to know if it is possible to create an average volume and average surface of several subjects without having to incorporate the Talairach transform and no transform at all.
Thank you,

You can just use the identity matrix. The white and pial surfaces will be bogus (probably the inflated too), but the atlas created from it will be valid
