AMBER: (no subject)

In essence I need to create a .crd file and a .parm file from a pdb file (which
was obtained from the Brookhaven database).

My problem is that:

1. When I load my pdb file into xleap it keeps adding countless atoms to the
system. I have tried using the "protonate" program to correct for mismatches
between the pdb system and the xleap system, but it keeps crashing out with the
following message:


a WRITE operation tried to write a record that was too long.

Encountered during a s sequential formatted WRITE to unit 6.

2. When I try to create a parm file using saveAmberParm <unit> something.parm
something.crd, it lists all manner of fatal errors.

My questions:

1. Is there a short and simple way of creating a parm and crd file from a pdb
file? i.e. not necessarily using xleap?
2. What is the principal difference in format between AMBER pdb files and
Brookhaven PDB files.

any help would be much appreciated
