I am trying to remodel the loop giving low-resolution electron density map. I have tried Rosetta3.2 and 3.3 however the job could not complete when I run in mpi mode. Could you have any solution for this?
The log of error is like this. It is due to mpi.
output filename: .//outdir_2/S_0003.pdb
ERROR: Unable to open file: .//outdir_2/S_0003.pdb
ERROR:: Exit from src/protocols/jobdist/JobDistributors.cc line:727
That code is still using the old job distributor. It wants you to pre-create (run_directory)/outdir_2 for it to put results in. Rosetta will create the output PDB files but refuses to create the output directory to put it in. I would guess you need outdir_0 through outdir_N, where N is the number of processors in the MPI job.
Exactly. For a loop modeling mpi job, you would need to create one output directory per processor to avoid that independent processes overwrite each others outfiles. The same is true for running jobs in parallel on a cluster.
