Hi, I want to study the interaction of two trimers of a hexamer system
with Amber 8 in redhat linux. I build a trimer first with the monomer
ann.lib and ann.frcmod. Then I save the trimer lib file as tri.lib and
then read in a hexamer pdb file and hope to write out the crd and top
files where two trimers are distinguished. However it seems that the
tri.lib can not be used together with loadpdb command any more even
for the original tri.pdb file. So why is the tri.lib different from
the ann.lib file which can be used with loadpdb tri.pdb for the
trimer?
Thanks.

The error message is like the following:
