I would like to select, for example, CA of GLY, CB of PRO, so I typed r
GLY& a CA | r PRO& a CB, but it doesn't work. make_ndx also doesn't
support parenthesis, either.
Previously, I used "r GLY& a CA" (save as group 1), then "r PRO& a CB"
(save as group 2), then "1|2", and finally "del 1", "del 1" to complete
my selection, but this is really not ideal!
Is there a easier way to do the selection in one step?
I would really appreciate it if anyone could give a hint.
