There are at least two places in the 1tgn file where two
residues are missing...the numbering skips two
numbers...if the residues are not known or "excised,"
souldn't there be some indication that there is a skip?
These are the locations that the display program
connects the residues...and I admit I don't know how the
program has decided to handle this kind of case...just
from my own experience, handling the exceptions in the
pdb file can be difficult!
I guess the thing that made me ask the questions
was that I couldn't match the numbering of the atom set
and the sequence set, which I would have expected to be
the same. I also was curious to find out what happens
when there are "holes"...how is the picture made? Maybe
if Dr. Sayle is in this thread, he may be able to answer
the question of how RasMol solves this problem.
Thanks again.
