I am having a hell of a time getting ANAL to believe in my groups for
energy decomposition.  I can find other emails to the list from people who
had this problem, but there are no replies to enlighten me.  Can anyone
give me a hint about this?
Many thanks, E
My analin file is this:

It reads in the coordinates, but not the groups.  Here's the analout:
