Currently, the dump group must be *all* for the *dcd* style. I just
wonder if it can be modified to dump selected group into DCD format. It may
help to reduce the file size in case there is massive solvent, which is not
yes. it should be doable. you have to take your favorite editor
load the dump_dcd.* files and implement it.
you have to make sure, though, that the group that you use
does not change the number of atoms and their identity, as
a .dcd file does not "allow" this.
p.s.: and if you're done with that, please apply the same
change to xtc format dumps. i know some people that would
be very thankful.
