Rosetta ab initio run gives 0.00 RMSD for generated 2000 models? (run still in progress)

Category: 
Structure prediction

Dear Friends, 

 

I am running ab initio rosetta run using openmpi:

 

mpiexec -np 16 /main/source/bin/AbinitioRelax.mpi.linuxgccrelease -database /main/database/ @options -mpi_tracer_to_file log > log1.log &

 

I see "score.fsc" file in the folder with 2000 models, and generated a RMSD vs Energy plot, whcih gives me this (the attached plot)

Modeling small molecules

Category: 
Small Molecules

Hi all,

Just trying to model a small molecule and how it interacts w/ my bigger protein in pyrosetta. 

 

I got this far: 

 

pose2 = Pose()

nonstandard_residue_set = generate_nonstandard_residue_set(pose2, ["ARA2.params"])

pose = pose_from_pdb(nonstandard_residue_set, "combine.pdb")

But pose_from_pdb only takes only 1 argument, how do I get around this?

How to get fragment library from robetta server for mre than 1000 residue sequence?

Category: 
Structure prediction

Dear Friends,

 

I am performing de novo structure prediction for a 1135 amino acid long sequence. I ran robetta server to generate fragments for my 1135 amino acid long sequence, but got the error : Sequence length must be between 27 and 1000 residues

Can you please et me know how to get fragments in this scenario? Thanks!

Can I use rosetta binaries built in one linux system to another linux system?

Category: 
Compilation

Dear Friends,

 

I have successfully built "mpi" binaries on my ubuntu 18.04. I want to run rosetta on my centos6.9 (with "Openmpi") machine too; can I simply copy the binaries from my ubuntu to centos  and run rosetta using "mpi" there? thank you!

how to make "static" built binaries use multiple cpus like "mpi"?

Category: 
Structure prediction

Dear Friends,

 

I downloaded rosetta static binaries "Rosetta 3.10 source + binaries for Linux - as one bundle (13G)"  on my centos6.9. I can see that  the executable in the "main/source/bin" are working, but how can I run these static executables (such as "AbinitioRelax.static.linuxgccrelease" ) on multple CPUs? Can I use "mpiexec" with these executables?

 

Thanks!

Error with RosettaAntibodyDesign when running antibody_designer.linuxgccrelease

Category: 
Design

Dear friends,

As a new learner of rosetta, I encountered an error "chain_id A represents more than one chain!" after I downloaded the 5ugy.pdb file from RCSB PDB database and renumbered to the AHo Scheme with PyIgClassify Server.

If anyone can help me with this issue? Any help would be appreciated.

Loop Modeling

Hi all:

      I am going to use antibody.default.linuxgccrelease to make a model for an antibody sequence.  The command I entered is ”antibody.default.linuxgccrelease -fasta mxp335.fasta -antibody::grafting_database  /home/mxp/apps/rosetta/tools/antibody >error1.log“.  I encountered the following error:

.......

I get the above error, can you please let me know how can I resolve this issue?

Thanks!
