OSC_Preprocessing Script & Synthetic bias fails

Software Siril
1

In the Preferences tab, Pre-processing, Master-bias: I insert =40 for my ASI533MC Pro (calculated as per tutorial) and check Use it as default, Apply.

I have lights, darks, flats and bias folders with appropriate data but nothing in the bias folders as I am trying to use a synthetic bias. Script fails when executing. What am I missing?

The problem is that you change the value in the preferences, but your script is not designed to follow what is in the preferences. If you want to use the synthetic bias, you have to modify the script.

Preprocess has been renamed calibrate. Are these two expressions equal?

preprocess flat -bias=“=256”
calibrate flat -bias=“=256”

Yes. We just changed the command name.
