Naming convention limited to 6 characters?

It seems the naming convention is limited to 6 characters?

I have OPLS naming conventions, like C136, H140A, H140B. The library_setup.py script, modifies the *mcf file to include _s1, etc. to the end of each species, but this addition is then not recognized by Cassandra, because it appears to only read the first 6 characters. So library_setup.py makes C136 C136_s1, but then Cassandra reads only C136_s and then gives me an error.

Is there an easy way to fix this in the script or otherwise? Really with some additions due to LOPLS recently, OPLS needs to allow for 5 characters in the name plus the 3 characters for "_s1", etc, so 8 total characters are potentially needed.

Thanks.
