There is/was a mni2tal script used in SPM.
I am not sure how 'portable' it is but you may want to look into it.

Subject: Re: [FSL] Talairach space registration
Our standard space images are in MNI space, not strict-Talairach
space and I'm afraid we don't have any conversion available.
As for relating the coordinates - the program tal2imgcoord
and img2talcoord (although they work with MNI, not Talairach
coordinates as they mis-leadingly suggest) give you the
ability to relate any voxel coordinate in the image (pre-aligned)
with the corresponding aligned coordinate given the images
and the transformation matrix.
Hope that does what you want.
All the best,
