[gmx-users] What's the best software to use: cut and past receptor and ligand

[Kai Zhuang]

Dear gmx-users list folks:

I'm trying to model a receptor and ligand system.  the receptor is
really huge and the idea
right now is to only model a part of the receptor (as in cut off the
irrelavent domains and focus on the binding domain).   the receptor
and ligands are in two seperate pdb files.

what's the softwares or some ways i can do the editing to put two into
the same file close to eachother as well as deleting the part of the
receptor tht's unwanted?
i've tried text edit it and that ended horriblly because i can't
manage the cordinates.
