Converting ngene to surveyengine format

How can I convert my NGENE design into SurveyEngine format?

This is now strightforward.
You can either upload your experiment directly into SurveyEngine - although you may need to recode levels to be offsets starting at 0 (then 1,2,3,4 etc)
or generate the design directly in surveyengine.
