Hi
Having not used PI for a while (and I'm only a beginner!) I came to take some images. I used the BPP script as usual to add in all the files / selected master dark / bias (no flat). These masters were created a few months ago. When I run the BPP script, it fails with this error:
*********************************************************************

I've tried changing the dark frame threshold but it doesn't seem to affect the outcome. Still fails.
If I run the light frames through ImageCalibration, with the same master dark / bias, I get no errors and a set of calibrated frames.
Does anyone know what could be causing this? Could it be the age of my dark frames?
It always used to work in the past.
Just trying to save myself some time with the script!
Thanks
Joe
