Hello Urszula
               I have tried to do by cada. But, I could not copy
"leaprc.zinc", "znb.lib", "hydroxide.lib" , "hin.lib" and
"frcmod.zinc" to the cmd, lib and parm folder. So, I have kept them in
that folder from where I am doing everything. I have changed HYS to
HIN , one GLU to GLH and the residue name of zinc to ZNB. When I give
the command "source leaprc.zinc" in xleap, some error massages are
coming. I load each library file in xleap. Then as soon as I load my
pdb file "2CBA.pdb" in xleap, xleap is vanishing. And, some error
message are coming in terminal. I have removed the last lines of pdb
file. So, what can I do?
