Hi everyone,

                As I wrote earlier that I am not getting the
outputs(topology and coordinate files) of my pdb file of a modified residue
by running XLeap despite of creating parameter(frcmod) and library (.lib
) files.I have attached all three files with this mail. Please help
someone.
