## relax.linuxgccrelease in multiple processors

Category:
Structure prediction

Hi, sorry if my question is naive.  But I would like to aks if it is possible to run  the next command in multiple processors and not in just one?

relax.linuxgccrelease -s model1.pdb -nstruct 1000

regards

and thank you

## Error in Ubuntu 20.10

Category:
Compilation

Hi, sorry for disturbing you but  I have problems installing Rosetta.  In Ubuntu 20.10.

I have also tried with clans, but it did not work.  I follow all the classical error list, but still no success. Also I am not sure what is the error.

regards

Constraints

Hello,

I am performing Rosetta ligand docking for an enzyme A to a ligand X which should be covalently bound to a small protein B.  I need to impose this covalent bond and some other catalytic constraints (distances between ligand and receptor's residues and also the distances between two residues of the receptors )  to my ligand docking.  I  found several movers for adding constraints including AddorRemoveMatchCsts, Addconstraints Mover, and ConstraintSetMover, but I am confused about which one works with Rosetta Ligand docking.

## [Solved] RosettaAntibody3 - Grafting step is failing to detect H3 from the input sequence

Category:
Structure prediction

I am trying to run RosettaAntibody3 to build an Fv hhomology model from an input sequence. I am following the documentation form here.

I am using the command:

antibody.static.linuxgccrelease \
-database \$ROSETTA_DATABASE \
-fasta /mnt/data/input/myinput.fasta \
-nstruct 1 \
-out:path:all /mnt/data/output/output-graft/ \
-detect_disulf false

which fails fairly quickly with the error:

## Error compiling mpi under Big Sur

Category:
Compilation

Using updated Xcode and a fresh install of macos Big Sur, I get the following error (below) when compiling using: "./scons.py -j 12 mode=release bin extras=mpi"

Open-mpi is installed (via homebrew) and if I run "ompi_info" all the info seems correct (see atached .txt). Any suggestions would be appreacited. Thanks!
