Hi everyone,
I’m trying to run Rosetta kinematic loop on my computer but I got an error message after few seconds:
ERROR: Cannot open PDB file “input_pdb”
ERROR:: Exit from: src/core/import_pose/import_pose.cc line: 184The comand that I have used and the screenshot of the error page is shown below:

How can I solve this problem?

in:file:native is only used for comparison to the output pdb, and other protocol-specific places. You want to pass the option in:file:s for the PDB you will be modeling.

Thanks everyone!

In Rosetta3.4 and before, the loopmodel application actually wants its input specified with the flag “-loops:input_pdb”.
In Rosetta3.5 and after, the loopmodel application uses the standard “JD2” input options. (So specifying the input pdb with “-in:file:s”).
