Batch preprocessing error

[Pelly93]

Hy guys.i've a problem with my pixinsight trial version!

Every time i start batch preprocessing procedure i get an errore message:

Cannot integrate less than three frames!


This message appears about the bias frames...but the problem is that i put in 15 bias to be processed!

I cannot understand what's the problem...any suggestion??

Can you post screenshots of both the error and the bias listing showing in the script window?

[Pelly93]

Hello,
I also have had this problem but not with bias but with darks and flats. I solved it by ticking the box "use master dark" .I do not understand why this did the trick, but anyway. So try ticking the box " use master bias" - that should do it.

[papaf]

Yeah, it seems the problem is after the bias, because it seems the script already wrote the master BIAS out.
Do you have darks also? How many of them? Also, tell us how many images per set you have (lights, darks, flats, ecc..)

[Pelly93]

i've got 15 bias 5 darks 14 flats and 20 lights... however i can try to tick the option of master dark 

[papaf]

That option is used when you already have a master dark generated by this script.
Can you post a screenshot of your darks and flats?

[Pelly93]

Yeah !! now the program works ...i've only tick the option use a master dark...even if i didn't have a master dark...  

[papaf]

If your dark is not really a master dark, though, it will do more harm than good.
If you want, post the screen with the darks.

[Pelly93]

ok...this is the screen with darks

One of your dark frames has an exposure time of 666 seconds. Since it's the only one, I think that is what's causing the error.

Yeah...you're right !!  thanks !!
