65536 is wrong, it should be 163842 (see Kara's note). If the data started in fsaverage space, then you just need to save the output as an mgh file (see MRIwrite()). You can then load it directly into tksurfer with the -overlay option.

Hi,
They have the same coordinates. Before I run MATLAB to obtain the analysis of anova, I mapped the cortical thickness value of each subject to fsaverage using mri_surf2surf and then I obtained the asc file with the coordinates of 65536 vertices and their thickness value. Now, I want to map the results of anova to fsaverage. Could these results do that? Or, you could recommend me another way to obtain the same map.
Thank you in advance!

If you are combining data across subjects in your matlab program, aren't they already in the same space? Bruce Fischl wrote: use mri_surf2surf. And you should have more than 65536 vertices/hemisphere. Usually the # is closer to 130,000 On Thu, 1 Oct 2009, Feng-Xian Yan wrote: Hi, I run all my subjects using recon-all ?subjid xxx ?autorecon-all.

Is it a functional volume? cheers Bruce On Thu, 1 Oct 2009, Feng-Xian Yan wrote: Hi, I have a problem want to solve. I want to map the data file (.xls or .txt) to fsaverage. What command do I type?
