Hi,
  There's an undocumented hack that can accomplish this in VMD
by using a per-atom data field to assign the ribbon thickness.
To use the hack, you would set this environment variable to the
name of the per-atom data field you want to assign the thickness from,
for example:
  set env(VMDMODULATERIBBON) user

The modulation value is simply multiplied with the existing
ribbon scaling values, so you would normally want it normalized
so the input domain spans from 0.0 to some maximum scaling factor.

Best,
  John Stone
