Well, either the N atom of residue 1 is not present in your .pdb file (in which 
case you've got a broken structure that needs fixing), or something else is 
going on.  Without seeing the contents of your input coordinate file (just the 
first residue, really) and your pdb2gmx command line, there's not much help 
anyone can give you.

thank you in anticipation.
