Yes, you can convert almost any registration file to a register.dat with tkregister2. See the --help.

mri_label2vol does not interpolate, per se. You can run into the situation where more than one label maps to a single output voxel. In that case, it uses the label that most frequently falls into the voxel.

Freesurfers,

I wish to use a concatenated .mat file created using FSL tools within the mri_label2vol tool. Is this possible? Is it possible to convert a .mat file to a register.dat file, which seems to be the format that mri_label2vol expects? Also, what interpolation method does mri_label2vol use, out of curiousity.
