Please help me with a Problem 'Ln: Invalid non-positive argument: ??'."

Recommended Posts

I am using WAsP Climate Analyst 11 and I've imported data, but when I try to see the results, an error window appears, that says:

"Could not refresh the contents of the corrections grid because ...
the system reported that:
'Ln: Invalid non-positive argument: ??'."

Can someone tell me why and what should I do, please?

Thak you.

Hi Jonathan, 

If I understand you correctly, this error occurs during data import in WACA 3.1. The error message does not reveal much, except that the program is taking the logarithm of a negative number as part of a data correction. The problem could either relate to the data or to an unusual option, maybe resulting in a data point with a negative wind speed. 

If the problem persists, I suggest that you take screen dumps of all steps in WACA import dialog windows and mail them to waspsupport@dtu.dk and include sample data and the version number found in the Help>About Climate Analyst...

Cheers, Morten

Hi Morten,

Thanks for your time.

No, I am new here and want to fix the issue. 

I used the sample data from Wasp; for example, the sample of Italy used data from 1997 to 2002, which showed me the same issue. I emailed the WASP technical team about this issue, but they have not responded.
