Hi all,
we are trying to run protien -ligand docking. We were able todo succesfully the tutorial and do for some of our drug molecules except "Diltiazem". we generated conformers using online tool [mentioned in the tutorial] and tried schrodinger conformers too. but the following error still persists. Screen shot is attached.
'Translate' mover" chain X doesnot exist.
We checked the conformers pdb file every conformer is seperated by 'TER' text and both PDB and conformers file has chain X.
we are in the process of manuscript revision with tight timeline and we are struck with this issue.

Post Situation:
The Translate mover isn't looking for chain X in the conformers file, it's looking for it in the input structure. (Roughly, what you've passed to -s)
The RosettaLigand movers assume that you already have some sort of starting complex of protein+ligand. RosettaLigand isn't a global pocket search - it assumes you already know roughly where the ligand should be, and have started the ligand off where it should go. The StartFrom mover that you have won't put the ligand into the structure, it will assume the ligand is already there, just in the wrong position. (It also won't complain if the ligand is missing.)
I'd double check your Diltiazem input files, and make sure that the Diltiazem ligand is present in your input and is listed as chain X in the PDB file you're passing to -s.
Attached are the input file, we used...
Everything looks to be in order, as far as I can tell.
Could you send me the full set of input files (including the XML) and the command line you used? Perhaps if I can run it on my local machine I can figure out what's happening.
