Setup will fail if .mol2 atom substructure ID matches filename

See original GitHub issue

This is very likely a niche issue (my very sloppy work found this error), but it may be worth sanitizing .mol2 files during setup–

If the substructure id for a atom in a mol2 file matches the filename, e.g.

20G.mol2
 47 48 0 0 0
SMALL
GASTEIGER

@<TRIPOS>ATOM
      1  C09       -2.7090   -4.5890    6.9990 C.2   203  20G      0.2532
      2  N10       -3.6170   -5.6600    6.6290 N.am  203  20G     -0.2986
      3  C11       -4.8540   -5.3500    5.9460 C.3   203  20G      0.0164
....

Then setup will fail with the following:

may also have problems with residue names that start/contain a digit

DOES have such problems.

I see—the problem is that we create the Topography from the Topology read in from the AMBER prmtop file in these lines, so we would have to

  • change the ligand residue name in the mol2 file to process it through LEaP
  • restore the ligand residue name in the prmtop file with ParmEd or search-and-replace
