Hello,
I am preparing a protein/ligand complex for MD simulation.
I used:
1. "antechamber -i rui_6058.out -fi gout -o 6058_rep2_pose1.mol2 -fo mol2
-c esp" this command to generate the mol2 file; (rui_6058.out is the
Gaussian output file, the files begin with 6058_rep2_pose1 is a small
molecule or ligand alone)
2. "parmchk -i 6058_rep2_pose1.mol2 -f mol2 -o 6058_rep2_pose1.frcmod"
command to generate the missing parameters;
3. Then I used Tleap to save the library of the ligand. I realized the
residue name of the ligand was changed to MOL. So I modified the
protein/ligand complex PDB file, also change the ligand residue name to
match the library.
4. When I load the protein/ligand complex PDB file into Tleap, I got
error. Unknown
residue: MOL (I also tried not to change the ligand name, I got the same
error, Unknown residue: L)
Could you help me solve the problem? I attached all the related files here.
Thank you.
Best regards,
Rui
