Title: Batch preprocessing script problem
Post by: Bob Hertel on 2012 May 02 15:57:52

Hi, all
I tried the script, but no matter what, I keep getting this message: "cannot integrate less than three frames".  Suggestions?
Thank you.

Hi Bob,

Welcome to PixInsight Forum. You need at least three images selected in each calibration set (bias, darks, flats) because this is the minimum that can be integrated. You need also three or more light frames if you enable the final integration option (it is enabled by default).

Hi, Juan,
Thanks.  I did put in a number of lights,but I used a master dark and a master flat for those sections.  If  you are saying I need to put in the dark and flat subframes, I guess I'm a little surprised, because that means we'd have to recreate the dark and flat masters each time,no?
Regards,
Bob Hertel

If you use masters for the darks, flats, or bias, you need to check the "use master dark"/"use master flat"/"use master bias" check boxes.
