psiphi

Function

Description

psiphi reads a clean coordinate file (CCF) of protein structure coordinates and writes a standard EMBOSS report file of psi and phi torsion angles in a specified region of a specified polypeptide chain. The angles are calculated for each alpha carbon (CA) atom from the co-ordinates of the mainchain atoms in the two planes around it.

Usage

Command line arguments

Input file format

psiphi reads a clean coordinate file (CCF) of protein structure coordinates.

Output file format

By default psiphi writes a 'table' format report file.

Data files

Notes

Clean coordinate file (CCF) of protein structure coordinates are generated by running pdbparse (in the 'structure' EMBASSY package) on a PDB file.
