Ligand Recognition #32

Hi,

I am trying to design a Lysine Binding Protein using LigandMPNN, but it seems that my ligand, which is lysine, is not being recognized. Could you please explain how LigandMPNN considers ligands? Is there a specific format or requirement for the ligand input that I should know? lbp_ligmpnn

lbp_atomrecord Thank you!

It worked when I changed the residue name to something other than an amino acid, like "LYY" instead of "LYS".

Had exactly same issue and worked. However if ligand atoms are in the following format they are not recognized either

Me too, same issue, I wonder how to fix it.

I can't see your image. Never mind, your image is nothing but copy from https://github.com/dauparas/LigandMPNN/issues/32#issuecomment-2196139897 I can your image from my gmail (automatic email from github due to my reply here).

Thank you very much. I just figured out it is the issue of occupancy in PDB files. The occupancy should be 1 instead of 0. For anyone who encounters this issue, it might be a solution.

You are my lifesaver. Thank you @lzygitk7 ! I had the same issue (no ligand recognition). Fixing occupancy solved!
