Centroid mode minimization

Structure prediction

Hi everyone,

I was wondering if there is something like the Relax Application but to use it directly in centroid mode. I know AbInitio uses fragment insertion to start building structures in centroid mode that are later fed to the All-Atom relax application, but is there something that can do a montecarlo local exploration without leaving centroid representation?

Rosetta Antibody: Unable to open file and terminates


Hello, please note I'm revising my posting with some major updates, apologies to the 9 viewers who have come here prior as this will read completely different.


I'm encountering a read error with antibody_H3. Below is the executable I ran (I've also reproduced the error with .static mode):

mpiexec -np 4 $ROSETTA3/bin/antibody_H3.cxx11threadmpiserialization.linuxgccrelease \

abH3.flags looks just like:

Confusion for Input Tutorial


Hi All,

I have downloaded Rosetta 3.11 and built it with using 

$ ./ -j 4 mode=release bin 

The building of the binaries seems to work correctly providing me with:

scons: done building targets.


I am now attempting to familiarize myself with Rosetta by traversing the tutorials starting with the Input & Output Tutorial so I am within this directory:

compiling with intel c++ compiler


Intel compiler has problem dealing with defaulted and virtualized copy assignment operator, reported here.

Because of this bug, compilation with intel compiler fails at `rosetta_bin_linux_2019.35.60890_bundle/main/source/src/protocols/genetic_algorithm/Entity.hh` line 55.

By implementing it explicitly, or removing "virtual" seems to be a solution.


Post Situation: 

running in MPI mode and multiple scores per output PDB file?


Hi Forum 
I recently did a Rosetta fixbb run with MPI and found that the score file had a lot more lines of output than there were actual PDB files. Specifically, I've got 353 scores in but only 12 PDB files.  is it possible that the parallel processors are simply overwriting the PDBs?   Is there a flag I should be including to avoid this?

Small Molecules

Hi all,

Anyone with experience with the GrowLigand mover?

I have as input a holo.pdb structure with a protein target of interest and a small molecule inhibitor which binds with low affinitty (parametrized to be used with genpot). 

I was hopping that this mover would return possible modifications on the ligand so I could rationalize my next steps of synthesis.

Here is my RosettaScripts:

cryptic error "Got some signal... It is:15" -- an issue with 'fixbb', or something else?


Hello Forum

I'm trying to run fixbb on my cluster here, and everything seems to have been going well for a while, but it suddenly stopped and spit out the following in the log file:

Speed problem when running RosettaLigand ligand docking


Hello, I am trying to do protein design using a protocol derived from RosettaLigand ligand docking.

When I run Rosetta Design as the following command line, everything seems correct and there are output structures (pdb files). The problem is that it takes ages to get the results. In average, it will take 15~20 mins to get one models. For 1000 models, it spent 9 days. I think there is something wrong, but I don't know how to solve it.

Fragment Generation

Dear fellows,

my recent situation with setting up the fragment generation for structure prediction ab initio consists in follow:

- It seems as if I solved my problems with version compatibility of gcc-compiler and the environment variable FRAGMENT_PICKER.

- But a problem with installation of updated and is still remained unsolved. I carried out next actions with the ncbi-blast-2.9.0+-src package:
