compute cluster/atom

Dear Lammps Developers,

I want to use compute cluster/atoms to group the atoms in a certain cut off distance.and finally I want to dump the positions of them and visualize it in vmd.
my problem is this compute gives each atom a cluster ID which will be the smallest atom ID of any atom in the cluster.but I need to know the real ID of atoms in the cluster to be able to dump the locations.
is there anyway that with this compute, I get the locations of clusters(atoms forming the cluster) so that I can visualize it in vmd?
if not would you please advice regarding that.

Best regards,

When you dump to a file you can include both
the atom ID and the clluster ID for each atom.
Isn't that enough info to post-process it into
whatever format you wish?
