Dear WRF-Hydro Team,

I encountered the following error during the calibration process while running calibOrchestrator.py:

Error in if (i2 == 1 | h2s < 0.1 | h2 < 0 | abs(h2) < (abs(h1) * 0.2)) : the condition has length > 1 Calls: cbind ... eval -> eval -> EventMultiObj -> eventIdentification Execution halted

Any help or guidance would be appreciated.

Best regards,
Fatemeh

oh, this is most probably since the testing period is small and it is not finding an event. Since those error metrics are not what I usually use or look at, I have just set them to -9999 to avoid running into this issue. In case you would like to do that too, here is my script. You could diff it with yours and make the changes on your end.
Thanks!
Arezoo
