An approach we have used in the past, if you have the original DICOMs
available, is to move the DICOMs with the volumes you want to remove (so
they are not with the others), and then rerun 'dcm2nii'. Then you'll get
a NIFTI volume, and corresponding bvec/bvals files with the offending
volumes eliminated, all in one step.
