In VMD Dynamic Bond Representation the Bond Radius can't be set below 0.1. Is there a way to do it using TK console? I want to reduce the bond radius further to like 0.08.
Try 'mol modstyle 0 0 DynamicBonds 2.0 0.08 10' command in the TK console (without the single quotes, tested in VMD 1.9.3). I've set Distance cutoff =2.0, Bond Radius =0.08 Bond Resolution= 10. Change them as you required.
