[gmx-users] make_ndx

Hello, gmx users:

In make_ndx, I would like to keep two groups, for instance, group 4 and
group 5. I have try it in two ways, namely, "keep 4 & keep 5" and  "keep
4 | keep 5". However both ways only keep group 4. Anyway to accomplish
my task is to delete other groups one by one, but it is not so
convenient. Could anyone tell me what is the trick? Thanks!
