Dear all,

Thanks a lot for your help with installing the built-in function. I have a question regarding the format of the imported candidate sets. The manual states that Excel files (including the new .xlsx and
.xlsm file formats), comma separated (CSV) files, semicolon delimited files, and tab ...

Dear all,

I am using the option of a candidate set import in Ngene, although I was faced with the problem. After I generated the design and saved it as the Ngene output file, I tried to open the saved file but Ngene showed me the blanc output. I have this design saved in Excel, but now I would like ...

Thank you so much for your help!
Helped me greatly.

Now I would like to ask additional question: Is that possible to fix two attributes in each task in such a way, that two attributes are fixed on the same level and only the other ...

Hello all,

I would like to ask additional question: after I ran the syntax specified earlier, I receive the following error: No valid design has been found after 1000 evaluations. There may be a problem with the specification of the design. A common problem is that the choice probabilities are too ...

Thanks a lot! It helps.

Best wishes,
