Hi Elahe,

I expect the jpg files do not have any header information like fits files, so some functions could hang. Could you convert to FITS instead of jpg to see if that works? jpg is lossy too, so you may want to avoid that format, but if you are working with color, then maybe fits is not good. in that case, TIFF may be better.

I noticed your comment "All is unchecked on the DP panel except,  Build and med on the bias subtraction", but could you post a screen grab of the DP Panel from your attempted DP run?
