II'm not that familiar with Mat Studio and car files, but perhaps
others on the mailing list can advise you. The msi2lmp program
should work in principle, but I am not he author or maintainer.
Also, you might look at other conversion tools in the tools
dir, e.g. chm2lmp and see if they will work - e.g. if you can
create a PDB file of your structure.
