We are experiencing issues with `mri_vol2surf` generating an incorrect surface for the `Paramagnetic.nii` volume. Although the registration file (`volume_transform.dat`), created using `bbregister`, appears accurate, the output surface file (`Paramagneticsurface.mgh`) does not look correct. Specifically, some voxel values in the cortical areas are incorrectly predicted as zero.
Command: ```bash input_volume=Paramagnetic.nii output_surface=Paramagneticsurface.mgh output_reg_file=volume_transform.dat
mri_vol2surf --mov "$input_volume" --reg "$output_reg_file" --hemi lh --projfrac 0.2 --o "$output_surface" ```
Any guidance on resolving this issue with the surface generation would be greatly appreciated.
your command line looks right. Try using the .lta file created by bbregister instead of the .dat file
