When trying to run a batch preprocessing I get the following error message "Cannot execute instance in the global context.
Reason: No master calibration frames or overscan regions have been specified." In the past I had got this error and went to BIAS tab and unchecked "APPLY ON OVERSCAN" box, and it fixed it. It is not checked now and I still get the same error message. This is a first run through with this data and I have no BIAS, DARKS, or FLATS. It is a brand new camera and I just want to see something!
Thanks,
Mick
