I need .gro, .itp, and .prm file for heteroatom for simulations of TM-proteins. Automated Topology Builder is not generating these files. Similar is the case with PRODRG? Any suggestions please.
It does not generate these file for GROMOS96_54A7. I have used LiParGen. But it does not generate .prm file for GROMOS. It does for Charmm but it results in error.
