Guys! the idea of having the cell parameter with just a simple command 
line is awesome. Some comments:
1. Would it be nice to be able to select the number of point the user 
wants in the quadratic regression. I noticed that 5 was used as a default.
2. Would it be nice to be able to see the py file that the command 
generates. In the same way, a general user would like to see the fitted 
data, in order to know by himself if the quadratic correlation is good.
3. Would it be even more nice to have a database with the experimental 
values. I mean, we all use a initial guess from webelements. GPAW could 
automatically use this values as initial guess.
These are just suggestions.
Best regards
