Dear AMBER Users and Developers,
I want to do a md calculation of protein-ligand complex using AMBER 8.
When I made topology file using tleap, tleap told the following message.
<><><><><><><><><><><><><><><><><><><><><><><><><><><>
+Currently only Sp3-Sp3/Sp3-Sp2/Sp2-Sp2 are supported
+---Tried to superimpose torsions for: *-N1-C7-*
+--- With Sp0 - Sp0
+--- Sp0 probably means a new atom type is involved
+--- which needs to be added via addAtomTypes
+Currently only Sp3-Sp3/Sp3-Sp2/Sp2-Sp2 are supported
+---Tried to superimpose torsions for: *-C6-N1-*
+--- With Sp0 - Sp0
+--- Sp0 probably means a new atom type is involved
+--- which needs to be added via addAtomTypes
......
.....
<><><><><><><><><><><><><><><><><><><><><><><><><><><><>
After that, I add the atom types, elements, hybridizations of ligand
molecule into leaprc file,
then tleap did not tell the message above.
Besides, I found that the result of md calculation was changed by the
addition in leaprc.
I don't know how these informations (atom types, elements, and
hybridizations) are used for md calculation.
Could anyone help with this question?
Thanks.
