External Email - Use Caution

Hello FreeSurfer Developers,

I am trying to smooth images using mri_surf2surf. Here is the command line:

'mri_surf2surf --s fsaverage5 --hemi lh --cortex --sval ',InputImagePath,' --fwhm 6 --tval ', OutputImagePath

The Input Image is 10242 (number of vertices) * 475 (number of time points) in the func.gii format. The output image is supposed to be in the same dimensions. However, it only smoothed the image of the first time point, i.e., the dimension of the output Image is 10242 * 1.

I have implemented this before but never met this problem. The only difference seems that I am now using freesurfer-darwin-macOS-7.2.0. Does anyone have any thoughts on how to solve this problem?

Thanks for the help,

Yangwen
