Hi Chuck,

PyMOL assumes your residues identifiers will be non-negative. Bad
assumption. PyMOL parses the string "-50" as the range "0-50". This
should be filed as a bug on the open-source tracker.

In the meantime, you will have to adjust all the identifiers in order
to select. If -73 is the lowest number in the sequence in chain J then
you can add 73 to add indices like this,

# adjust the indices

alter chain J, resi=str(int(resi)+73)

# update the sequence

sort

Now, just add 73 when you select:

select c. J and i. 0

Cheers,

-- Jason
