[gmx-users] pdb does not work.

Just as a test run I wanted to see if I could simulate 5 repeats of glycine.  I give the command:

pdb2gmx -f PGly.pdb -p PGly.top -o PGly.gro

and I tell it to do:

0: GROMOS96 43a1 force field

The output I get is:

Program pdb2gmx, VERSION 3.3.1
Source code file: resall.c, line: 438

Fatal error:
Residue '1' not found in residue topology database

Why is it giving me this output?  Here is my pdb file and thank you for your help :)
