dihedral circle


Dang reads coordinates from a Protein DataBank (PDB) molecular structure file and generates a table of several useful geometric measurements for each residue or base. In its most basic form, it writes out dihedral angles (phi, psi, chi) hence the name. The output is formated for easy parsing by awk, grep, sort and other UNIX utilities.

Scripts for parsing Dang output into delimited tables are available on the scripts download page.

For the most part, Dang has been replaced by Dangle.
