Hi,<br><br>I've been unable to figure out how to colour the electrostatic surface of a protein red/white/blue. I'm assuming that you have to some how assign electrostatic potential before colouring but how is this done? I'm using a Mac and I've tried to use apbs with pymol but it will not recognise my pqr file generated on the pdb2pqr server or generate it itself.
<br><br>Thanks,<br><br>Kate<br>
