Hi folks. I am using the script/batch prepprocessign. I add in my darks, add in my lights, and my bias. then I run the script and I get this error. NOTE: I did not have the master darks button selected but after it runs and bombs its checked!!

The error I get is

ImageCalibration
Cannot execute instance in the global contect
Reason: No master calibration frames or overscan regions have been specified.

Any suggestions on what I am doing wrong?

Hi, I suggest you go through the steps of BPP in this section to check what is missing in your settings.

Saludos, Alejandro.
