helicity_check shows the evolution of O—N distances over an amino acid sequence
See for further info:
"Models for the 3(10)-helix/coil, pi-helix/coil, and alpha-helix/3(10)-helix/coil transitions in isolated peptides". Protein Sci ROHL and DOIG 5 (8) 1687.
Uses:
>run pymol_helicity_check.py
----> select some consecutive amino acids
- this is nicely done with the Display->Sequence tool
>helicity_check()
- installing helicity_check
copy pymol_helicity_check.py in $PYMOL_INSTALL_DIR/modules/pmg_tk/startup
launch Pymol: you now have a new option in the Plugin menu
helicity_check uses gnuplot to display its results.
As a consequence gnuplot needs to be installed.
This plugin was tested on linux only, it might need some modifications to run on
other OSes. (hints: launching gnuplot and path to dumpfile)
