  Can you be more specific please?  My first interpretation of this
question is "if you only have one group why do you need to fit a mixed-
effects model?", but with further explanation you might get some useful
advice.

  Also, it would be best to follow up to r-sig-mixed-models at r-project.org
where you can get more specialized help with (n)lme.
