Per the manual, this usage is not supported. You can use a groupid
(without a '%' modifier) to find residues with atoms within the cutoff
from atoms in the group.

Allowing the '%cmass' and '%center' options makes some sense, and
I am looking at implementing it. One issue raised is whether to
allow residues in the group itself to appear; in the current
distance-from-group version they are not output. Does anyone have
an opinion?
