To elaborate a bit further, Tcl evaluates the inside of strings for
commands inside of brackets, since those are evaluated first. This
causes a parser error, since ... isn't a command. The way this is
handled elsewhere is to selectively escape brackets, so changing the
offending line like so:
vmdcon -info "J.V. Vermaas et al., TopoGromacs: \[...\]"
or simply commenting it out will also fix the error. Thanks again for
pointing out the problem!
