Hi everyone,
I'd like to create a script which allows me to do some basic stuff like
calculating a height distributiona and then fitting a gaussian to this
data on a lot of data sets. So doing it manually is not an option.
I found two modules who could be usefull for this:
stats and sfunctions
but the problem is, Gwyddion crashes without any error message or
something similar when I call these modules. I checked other modules
like the "fft" which works fine and without problems. I added a sample
script in the attachement. It would be nice if someone could say
something on this.
Btw. using the implemented function "dh" of the DataField was not
suitable up to now because I'd like to do some more data processing
befor I want to save the solution somewhere and up to now I didn't find
a way to get a DataLine into a Graph or something similar... :-( So a
hint on this would be helpfull, too.
Regards,
Denny
