I got rid of the protG example, primarily because it wasn't useful  
for showing people how to
use marvin to solve structures.

The peak tables included in the CVN and IL-4 examples contain many  
bad peaks.  They were
generated by automatic peak picking using Dan Garrett's CAPP  
program.  After the initial matching
of peaks to shift assignments and filtering the resulting peak  
assignments, about 10-15% of the
assigned peaks are completely wrong.  More importantly, a very large  
number of wrong peak assignments
are still attached to good peaks (i.e., peaks that have another,  
correct, peak assignment).

And as we showed in our 2005 JACS paper, adding wrong peak  
assignments to otherwise-good peaks
is, for the behavior of marvin, entirely equivalent to adding  
completely new, entirely wrong peaks.

If you're really interested, the protG example is still available in  
older versions of xplor-nih.
