Technical Information
The following scene demonstrates a problem with greek letters in labels in Jmol
- (using δ in the label, it gets corrupted)
Script for translucent MEP colored surface:
{hydrogen}.partialCharge = 0.41
{oxygen}.partialCharge = -0.82
# IMPORTANT: the SOLVENT version of isosurface
# IGNORES WATER UNCONDITIONALLY! We must us MOLECULAR!
#isosurface resolution 6 MOLECULAR colorscheme "rwb" map MEP
isosurface resolution 6 MOLECULAR map MEP
# Higher values of resolution make a choppier surface that rotates
# more jerkily. 6 is good.
color isosurface "rwb" range -0.2 0.2
# chose this range by trial and error.
# default is -0.1 0.1 as reported by the isosurface command.
color isosurface translucent 2
# or the partial charges could be in the PDB file using
# this command to transfer the values.
# {*}.partialCharge = {*}.temperature.all
Possible script for large translucent hbonds:
select all calculate hbonds hbonds 0.3 color hbonds white color hbonds translucent 6
