Hi,
Thank you for your suggestion. But, I run the MATLAB under windows XP, because I can’t setup the MATLAB under LINUX. I don’t know what’s wrong, and now I only run MATLAB under windows XP.
So, when I did anova command to obtain F value and p value using MATLAB under windows XP. I save these values in xls format. Then, I would like to map F value and p value to inflated surface of fsaverage, respectively.
Could you tell me how to do and what command do I type? And, what’s the functional volume?
Thank you in advance!

The easiest thing to do is to specify your output of mri_surf2surf as mgh format instead of curv. The read that directly into matlab with our MRIread() matlab command (ie, no mris_convert stage). Make your computations in matlab, then write them out as mgh format using MRIwrite().

Hi,
The mri_surf2surf command line was
mris_surf2surf --srcsubject xxx --sval xxx/surf/lh.thickness --sfmt curv --hemi lh --trgsubject fsaverage --tfmt curv --tval fsaverage/surf/lh.xxx.thickness
mris_convert –c fsaverage/surf/lh.xxx.thickness fsaverage/surf/lh.white fsaverage/surf/lh.xxx.thickness.asc
From these two command lines, I obtained the asc file with the coordinates of 163842 vertices and their thickness value.
Then, I did anova analysis to obtain F value and p value using MATLAB.
After I obtained the results from MATLAB, I want to map these results to inflated surface of fsaverage.
Could you tell me how to do and what command do I type? Or, you could recommend me another way to obtain the same map.
Thank you in advance!

what was your mri_surf2surf command line?

Hi, But the number of vertex I obtain using mri_surf2surf is 65536 each hemisphere. So, how can I do to make the number is closer to 130,000? Thank you in advance! Feng-Xian 2009/10/1 Bruce Fischl <fischl@nmr.mgh.harvard.edu <mailto:fischl@nmr.mgh.harvard.edu>> use mri_surf2surf. And you should have more than 65536 vertices/hemisphere.

Feng-Xian 2009/10/1 Bruce Fischl <fischl@nmr.mgh.harvard.edu <mailto:fischl@nmr.mgh.harvard.edu>> Hi Feng-Xian have you run recon-all on your anatomical data? What kind of data do you want to map? 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?
