Hello,

I have a particular protein structure in the format of a pdb file that has been "touched" by a non-VMD program.

If I load this pdb file into VMD and use a selection such as "not protein" I expect the protein structure to not be displayed. However it is still displayed.

as described here "protein" is
http://www.ks.uiuc.edu/Research/vmd/current/ug/node89.html#5192
a residue with atoms named, C, N CA, O
The first few lines from my troublesome pdb file are shown and the requisite atoms exist.
