[Chimera-users] [Chimera] Failure preparing structure for Autodock Vina

Dear Jutapat,
The chimera-users address (CC’d here) is recommended  for questions, for your future reference.  Email to me only might fall through the cracks.

It is hard to tell what the problem is without having your data, but the message says it cannot figure out the atom type of some atom Ha, so maybe the hydrogen atoms in your input structure have weird names or the names are in the wrong columns of the file.

You might try deleting all hydrogens (e.g. command: delete H) before running the tool.  However, if that doesn’t work you probably need to correct some error in your input file (the file format or atom names in the file).
I hope this helps,
Elaine
