if you load two prmtop/prmcrd files (or a mol2 file) into VMD a bond
(if it is correctly defined) should be displayed independently of its
length. I do not think there is a threshold here. This can be easily
tested using a model with a very long S-S disulfide bridge between two
CYX residues for instance...
if you load a PDB file without any atom connectivity into VMD a bond
should be displayed ONLY below an internal threshold; Yes.
if you load a PDB file with an connectivity for a very long bond: to
be tested ;-)
regards, Francois
