The .atp file is only read by pdb2gmx, so it's not relevant. Apparently
you have an atom type "1" (number one) in your topology, which is very
strange. It doesn't have parameters defined in gb.itp, so you get a
failure. Make sure your input is sound and your topology/force field
files are free of typos.
