I no longer stack using dark calibration frames, but I do still use bias frames. I have folders containing captured bias frames for several different ROI% settings to use with lights of the same ROI%. I want to use the Pre-processing script OSC_Preprocessing_WithoutDark, but would like to not have to always copy 50 large files over into the home directory of Siril when doing a stack. I hoped that I could get around this by telling Siril to use a master bias file as default, by selecting that file in the Pre-processing area of Preferences. I retrieved a master bias fit file that was generated in a previous run of the OSC_Preprocessing script and copied it into a new folder D:\Siril\Bias_Masters. I then browsed to and selected that file in the Pre_Processing GUI and checked the box for “Use it as default”. But when I then run the OSC_Preprocessing_WithoutDark script it still goes looking for a folder named biases in the home folder.
What is the best way to achieve having that master bias file that Siril always uses by default so that I don’t have to copy the whole biases folder from my calibration library for every stack?
Thanks,
