Error msg while compiling on a new cluster


Not sure why scons is failing on a new cluster

>./ bin -j16 mode=release extras=mpi

I see en error:

scons: *** Do not know how to make File target `bin' (/usr/projects/xyz/shared/rosetta_3.10_release/main/source/bin). Stop.

rosetta_3.10_release could be easily compiled on my local machine.

Error with etable_atom_pair_energies()


I am new to Pyrosetta and programing and I am learning how to use Pyrosetta. So when I was practicing scoring with Workshop #3 bullet point 5, I came across a error, and I have no idea what's wrong with.

Here is what I did. 

r1 = pose.residue(24)

r2 = pose.residue(20)

a1 = r1.atom("N")

a2 = r1.atom("O")

etable_atom_pair_energies(a1, a2, scorefxn)

Rosetta_CM error unrecognized atom 'CS' this atom is not in PDB

Structure prediction

Hi all,


       I'm sorry if this is an old thread, I did find other forums dealing with unrecognized atoms but in those threads my problem was not resolved.  I am trying to follow the rosetta_CM tutorial and I got through the script and it generated the .xml file which I checked and it looked good. However, when I run the hybridized steps using rosetta scripts I get this error:


ERROR: unrecognized atom_type_name 'CS'

Hi Rosetta users,

I am experiencing trouble using RosettaMP to predict membrane protein structures. I am currently following the RosettaMP tutorial, which can be found here (

Build problem "Never include <bits/libio.h> directly; use <stdio.h> instead."


Hi everyone,

I am trying to build Pyrosetta from source in Ubuntu 18.04 x64, but  I am having a compilation error, as indicated in the title.

Does anyone have a clue about what could be the issue or has a better idea to compile it?

I am using python 2.7.15, rosetta build 2018.33.60351, ninja 1.8.2, cmake 3.12.1 and gcc 4.8, specified with the global variables: CC=gcc-4.8 and CXX=g++-4.8. The error log is:

Problems when working with PTMs - cannot make sugar poses

Chemically Modified Residues

Hello everyone,

I have a protein which has a few PTMs in the form of sugars, and I have therefore started experimenting with sugars in PyRosetta. I have found a very nice guide:

which I have used as a starting point together with the documentation e.g.
