As Dave said, it would be best to post the actual input you tried, and
if you didn't get the result you expected something we (I) could use
to reproduce the issue (topology, coords, input, etc).

The 'align' command is just a bare-bones implementation of best-fit
'rms' without creating a data set or any other functionality like
per-residue rms calc. etc. Guess I should be more clear in the manual
(boy if I had a nickel for every time I said that...).
