I actually enjoy a good mystery, and downloaded this structure, wrote the C chain to its own pdb and loaded it alone to see if it would solve the problem... it did not (hence my not posting anything). There are also no odd indicies or names that would obviously cause a stride error. I'm stumped, and am really curious to see if anyone comes up with an explanation.

Could it be that stride gives and error if the selection is too big? There is a limit of 10000 hbonds. Not sure how the other viewers calculate the cartoons.

Hi all,

I hope that somebody here can help me solve a mystery regarding a newly released pdb 4G7O. Chain C of this protein can't be visualized using the ribbons or cartoon representations. Some smaller sections of chain C that I have removed and put in to a new pdb files show up fine in new cartoon representation. pyMol, jMol and other visualization software packages handle this structure with no problems, displaying all of chain C.

What could be happening in VMD that would cause this kind of problem in the cartoon representation of chain C?

Thanks in advance for your help!
