When posting build/install question please specify the following information about your system and PyRosetta version, this will allow us to answer your questions more accurate and faster:

- OS type,
- OS version
- OS arch (32 or 64bit)
for example: Ubuntu Linux 10.04 32Bit or Mac OS X 10.6

- Python version
- Python arch (32 or 64bit) if different from OS

- Version of PyRosetta including SVN revision number.

Thank you!

What is the expected behaviour when minimizing a jump edge?


I have seen references to minimization of a jump edge (e.g using a MinMover object) leading to both rotations and translations downstream of the jump. 

I am modelling an interaction between two proteins, connected in the fold tree by a single jump edge, with atom pair constraints defined to bring them into close proximity.

I allow movement of this jump in the movemap (set_jump), atom_pair_constraints is activated in the scorefunction, and the fold tree is valid.

Minimization not changing jump edge vector length


I have written a script using PyRosetta (pyrosetta-4.0-py2.7 retrieved from github 2017-05-23) which:
- imports a PDB file containing a full antibody structure and antigen dimer separated by around 100A
- defines a custom fold tree with the Fc at the root and a jump edge connecting the Fc to the antigen
- creates ambiguous site constraints consistent with interaction of variable loops of the two Fab domains with the epitope of each antigen in the dimer

Rosetta compilation on Linux Ubuntu


Hi everyone,

I downloaded the rosetta package for linux (version 3.8). During the compilation I receive an error saying: 

UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 102: ordinal not in range(128)
scons: building terminated because of errors.

Can someone help me to resolve this problem. Thank you.

how to generate the whole molecule that contains all the symmetric chains


Dear all,

I have a pdb file which contains three chains (A, B, and C) for a protein molecule. According to my knowledge, the protein should be 3-fold symetric and a trimer of the three chains. Is there a way to generate the pdb file which contains all the 9 chains for the whole molecules?  I can only find some infomation from the original pdb file about the symmetry like these:

Interesting scoring performance in flexpepdock against random peptides


Dear all,

recently I have tried to dock some different peptides to binding pocket of protein kinase and see their performance in flexpepdock. In the meanwhile I also dock some random peptides, such as poly G (GGGGGSGG) and poly E peptide(EEEEESEE). Interestingly, the energy score of good peptides and random peptides didn't show much differences(from -650 to -690), sometimes the random peptides even showed the better energy score. In order to keep them in the pocket I have made some constraint. The orientation of peptides are similar.
