Hi,

Check whether your starting and ending date of the simulation and observed do match.

regards,
Yonas

hi, 

I don't see any problem with your start and ending date except the way you set .gw parameters. Normally, .gw parameters are replaced so instead of r use v as prefix (v__GWQM.gw).

regards
Yonas

Hey Yonas, thanks for your effort. But the problem remains same even after changing the prefix to v.

Hye Prantim,

 I had the same problem before, and it was because the observed .txt file was not in the correct format. Once I corrected the file formats as specified in the following link, the issue was resolved. You can also check that link—it might help you fix the problem.
