Hi, I'm starting to work on running simulations of interactions between
proteins and CNTs. I generated my CNT using the make_arm.tcl code from the
"Simulation of Water Permeation Through Nanotubes" tutorial. I then
downloaded my protein from the PDB. I tried loading them both into vmd and
then writing them to one file but when I do that some of my carbon atoms
have their coordinates set to {0 0 0}. Is there a good way of doing this?
