Question about the error I met when fitting the SQ model #49

Hi, I tried to fit the SQ model using my own data which is in the same structure as phenocam_DB and contains no NA, but I got this error message (Error in [.data.frame(T, loc_rising) : undefined columns selected) and I didn't know how to solve. I guess perhaps something went wrong when I call function triangular_temperature_response. When I tried to fit the AT model, it worked well and didn't meet this error. So I am wondering if you have any suggestions about the potential problem in my code. Thanks.

Check of the ranges of the parameters for the temperature function are reasonable. If their domain is too narrow you might run into problems during optimization.
