The contents of a coordinate file (any format) and a topology must be the same 
in terms of the number of atoms, their order, and their names.  Topologies can 
be made from coordinate files (using pdb2gmx), but coordinate files cannot be 
made from topologies.  There are various programs capable of creating coordinate 
files, but there is no guarantee that they match an existing .itp file.  Any 
corrections (atom names, atom order) usually have to be made in a text editor.
