Black image after ImageCalibration, when input is RAW

[zvrastil]

Hi,

I have strange problem with ImageCalibration. When I apply it to RAW (CRW) images, it produces completely black (0) image. When I first convert RAW image to FITs using BatchFormatConversion script, it produces nice calibrated image. Is there some piece of knowledge I'm missing?
Attached image shows my options. I integrated darks without bias subtraction, so darks need to be calibrated. Flats were already bias-subtracted before integrating master flat.

thanks, Zbynek

Hi Zbynek,

I haven't seen this problem before. All settings look perfectly normal, so you probably have discovered a bug. Could you upload a couple of lights and your master bias, dark and flat frames? I guess it's the only way I can understand what happens. Thanks!

Sure Juan,

I'll upload them to pixinsight FTP this afternoon.
