compute group/group's output

Dear all,
How can I write the data from “compute group/group …” into a text file?
I have tried “fix ave/time” . However, nothing was written in my file!
It seems, “dump” can not be used, can it?


Compute group/group proudces scalar values, not
per-atom. So it can't be written into a dump file.
But it can be output with thermo info (try that first),
and it can be used as input to fix ave/time, which
will write it to a file. So you must be doing something
wrong if that didn't work.
