Relax_fit.py problem -- October 08, 2008 - 17:10

Hello,

It seems that Relax_fit.py requires replicate data because average and 
standard
deviation values are used downstream in the analysis. With no replicate data
(since I don't have any) the output is shown below. Also, commenting out the
average and error propagation across multiple spectra

#relax_fit.mean_and_error()

doesn't work either, and I get another error output that is looking for an
averaged value. I'll probably try using a duplicate data set to circumvent 
this
for now (unless this is actually another problem).

Output:

relax> relax_fit.mean_and_error()
