[Chimera-users] Webgl, python script for multiple pdbs

[Tom Goddard]

Hi Avnam,

  Possibly the problem is that Chimera has not drawn the atomic model before you export the HTML and it may not show the ribbon or atoms until they get drawn on the screen.  I am not sure about this.  (All our development is on our newer ChimeraX program, although it does not export WebGL/HTML.)  To get it to draw put in a rc('wait 1') before you export the HTML.  If that does not fix it, make sure to try with the exact same PDB file doing the steps by hand to see that it is not some issue with the specific PDB file you are using.

	Tom
