Conversion from Dihedral angles to Cartesian coordinates

Question

[physicsvigna]

I want to convert given bond angles, bond lengths and Ramachandran angles to cartesian coordinates for a given sequence of an amino acid (or for a protein). Is there any software which can do this? I heard that Rosetta can do this. Can this be done in BIOpython. I have seen a module called BIO.PDB. However, it is not explained how to use that module.

Yes, it can be done in Biopython and was added pretty recently: https://github.com/biopython/biopython/pull/2399.

See page 196 of http://biopython.org/DIST/docs/tutorial/Tutorial.pdf for some documentation.
