## Chain name being read as residue

Category:
Docking

Hi,

I am attempting a ligand docking run in a P450 docking both the heme cofactor and ligand simultaneously. I was able to have a successful run with just the heme group but when I attempt to add in the ligand I get an error. Currently, I've been getting the error "unrecognized mm_atom_type_name W" where W is the chain name for my ligand. I've attached my docking file, initial structure pdb file, and my options file so they can be looked at to help me resolve this issue. Thanks in advance!

## Problem importing residue params file

Category:
PyRosetta

I have been trying to load 'HYP.params' for the hydroxyproline residue. According to previous answers in the forum there are 2 options: add the params file to the residue_types folder and editing the residue_types.txt or loading the params file via command lines in pyrosetta. Neither of these options work for me and raise the following error:

Hi,

I am trying to model a loop with a constraints file (the constraints are for the atoms of the loop).

but every time I get this message:

I also tried to set the flag "-constraints:named" to true but it didn't help...

Hello,

I am performing Rosetta Ligand docking for a ligand, let 's say A . The ligand A is in contact with both water and water vapor. I have two main quesions and I would really appreciate your help in this regard:

1. Do I need to explicity consider water in my docking as a separate ligand with the ligand A? Or is the implicit solvation in scoring function sufficient?

Dear All,

Based on "https://www.phenix-online.org/documentation/reference/rosetta_install.html" I have installed the recent rosetta_src_2020.08.61146_bundle, and I have included "export PHENIX_ROSETTA_PATH=/your-path-to-rosetta-here/" in my .bashrc and have it sourced, with"/your-path-to-rosetta-here/" as the directory containing "demos   main    tools".
