Rainflow Analysis on Imported Signal

Is it possible to use the rainflow procedure within Dewesoft on an imported signal rather than use another software Matlab for example. I have the fatigue module license. I guess you can do statistical analysis on an imported signal which would help somewhat - but the important step is deriving the range regardless of polarity. Thanks.

It is possible to do Fatigue analysis on imported data. In Dewesoft it is possible to import the data in txt format.
