Hi,

I do not have a good understanding of the mri_vol2surf command.

1) Can this only project the part of the volume that lies between the white & pial matter?

2) What is the default projection parameter that it uses?
3) Does projection always start from the white matter, i.e. is 0 the white matter surface?

4) What is the nature of the mgh file that is created by:
mri_vol2surf --src mri/spmT_0002.img --regheader s04  --interp nearest --hemi lh --o lh.sig.mgh

Thanks,
