Have a close look at my original text:

[edward@localhost ~]$ mpirun -np 5 /data/relax/tags/4.0.2/relax
--multi="mpi4py" -v
relax 4.0.2
[edward@localhost ~]$

Note how "relax 4.0.2" is on a different line - that is the relax
output, not the command line input.  Try again without that text.

This is because the double-dash to single-dash conversion is only in
the HTML version of the relax manual, and not emails.  Run "relax -h"
to see a description of this option.

You should set your alias to the relax-4.0.2 version instead.  The
2.2.5 version is very, very old, and many bugs have been fixed since
then.
