I am trying to use make_ndx to make a group with multiple atom ranges.
E.g.
a 1-50 80-120 150-200
I can not use the minus symbol “-” twice when doing so. I tried using & or | and I am not able to do so. Do I have to list each atom # individually after the first minus sign or is there an easier way. I have a long list of ranges for the atoms I need to group.
That did not work for me. I tried entering ranges a 4018-4044 | 4159-4176, but I get this notification Syntax error: “-4176”. When I try a 4159-4176 alone then it works fine.
