The list does not accept attachments. If Gromacs is interpreting "LIG" as "LI"
then the .pdb file is formatted incorrectly - at least one column is shifted,
which will lead to misinterpretation of all of the contents. If you want to add
a new residue in the .rtp file, refer to the manual, section 5.6.1, in
conjunction with implementation details at:
