Well, I didn't shuffle or sort my system prior to running. I am running in
parallel, would that be part of the problem?
I have tryed -fit or -pbc but the structure comes out bad the same way. The
exact problem is that I have two structures. Each comes from individual
dynamics job. Now I need to align them so that I can run another job to
study the interaction between them. I have tryed using spdbv and sybyl for
that. spdbv completely mess up my structure. Sybyl tells me that there is
more than one model in my file, and how many of them I would like to load.
Chimera works, but I cannot seem to be able to join both structures and
manipulate them in order to obtain the starting positions for the structures
that I want.
Thank you in advance
