Index selection by group name
When selecting an index group by using its name the routine that parses the input does not catch an error where it should. See:
Just take any pdb you like, get an index file
echo q | make_ndx -f x.pdb
editconf -n -f x.pdb
and select, e.g. "MyBackbone", or "FIRST_sol", or "Protein_Part1", then editconf will not report an Error, but select backbone, SOL or Protein.
Within a larger script this can cause nasty bugs as you don't get an error (Which happened to me).
