RotaMol is a user-friendly program that allows rapid analyses of protein size during viewing/editing in PyMOL.
Wrote this a while ago and have been coming up with slight improvements every now and then when I get free time, so the source isn’t really "finished", but it works well.
This script, named RotaMol, has to be used in conjunction with a protein modelling program called PyMol (not written by me). So if you dont have PyMol you wont be able to test this.
Once your protein is loaded into PyMol this script will essentially calculate the area of every face, for a user defined level of accuracy (pixelskip) and angle of rotation. It is then calibrated using the Zoom function in PyMol, and it spits out the average rotational area of the protein in Angstroms squared.
Included here is the source,
Also is a link to the Google code page where it is hosted for Full .EXE download, as well as all documentation - tutorials - back versions, and a more in depth description of how it works and various links,
latest version should be on top
