Hello travis,
good news, and thanks for your last comment. However, using nans give some 
errors with scipy.stats:
lionel52>t=array([1,2,nan,4])

lionel53>stats.nanmean(t)
---------------------------------------------------------------------------
exceptions.NameError                                 Traceback (most recent 
call last)

/home/lionel/<ipython console>

/usr/lib/python2.4/site-packages/scipy/stats/stats.py in nanmean(x, axis)
    258
    259     # XXX: this line is quite clearly wrong
--> 260     n = N-sum(isnan(x),axis)
    261     putmask(x,isnan(x),0)
    262     return stats.mean(x,axis)/factor

NameError: global name 'N' is not defined
