Error when trying docking protocol with different ligand



I'm coaching an iGEM team at the University of Warwick and they're doing some dock design to try to switch the specificity of a transcription factor to a different ligand. We've been able to run the docking protocol with the protein and it's native ligand and it is able to recapitualte the the native binding. However, when we try the docking protocol with the new ligand we run into this error:

str::out_of_range with mpiexec and relax


I'm doing a very simple relax to optimize and score 100.000 pdb files.

Rosetta was compiled with MPI+MYSQL support. 

If I call the relax application on a single PDB file, it works.

Since I have a 64 core machine + 196 GB RAM (with MPI installed), I would like to relax 63 structures in parallel.
This is the command i'm executing with MPI:

mpiexec -np 63 /rosetta2020/main/source/bin/relax.mpimysql.linuxgccrelease @relax.flags.database

Trouble installing Pyrosetta


Hi, I had some problems downloading Pyrosetta (macOS 10.15.3 Catalina, python2.7.16, Pyrosetta-Release-2.7 from download page on website). After unzipping and running the setup command, I tried to import the pyrosetta library (import pyrosetta; pyrosetta.init() ) but got the error message

Traceback (most recent call last):

  File "<stdin>", line 1, in <module>

  File "pyrosetta/", line 15, in <module>

    import pyrosetta.rosetta as rosetta

Setting output values using a database (with relax app)


Hello all,

I noticed rosetta creates 23 tables in MySQL when using it as output backend in the RELAX application.

For my specific research I only need to hold the per-residue energies and the total energies... I don't need the atoms, topology or PDB data to be saved after each cycle, as it consumes a lot of memory.

BUG REPORT: MySql column protocol.protocol_id must have the AUTO_INCREMENT flag set


I tried running relax compiled with MPI and MYSQL.

MySQL was configured properly. A test run without MPI successfully created tables and wrote data to MySQL.
The protocol file @relax.flags was created with the following options:

-list pdblist.txt
-relax:script relax.script
-relax:bb_move false
-score:weights res2015

RosettaDesign error with Option file open failed


Dear users and developers,

I was running RosettaDesign and an error was reported as "[FILE]: src/utility/options/

[LINE]: 536


Option file open failed for: '/**/general_FD.flags'".  

This flag file worked on other server previously. Is this an error with compiling Rosetta or with the flag file? Could anyone please give some suggestions about how to fix this? Thank you so much.
