Thanks Bruce!

mri_surf2surf does not accept a curvature file as an input. So we are thinking to make a .nii file with curvature values and pass it to mri_surf2surf. In case you have a simpler solution, we would be happy to hear it.

Best,

I think mri_surf2surf can be used to smooth the sulc on the surface (as 
opposed to changing the way that the inflation works)

Hi,

We have used mris_inflate:

mris_inflate rh.smoothwm rh.inflated

The command generates inflated and sulc files. We would like to do a little bit of smoothing on the sulc file, so that we get rid of few scattered regions where small positive curvature islands are located within negative curvature areas (and vice versa). How can we achieve this?

mris_inflate has two options: -n and -dist, but assigning different values for these options doesn't seem to have any effects.

Thanks,

Reza
