I've uploaded some files to illustrate the difference.  This directory contains the original RGGB file as well as the files generated by AIJ and ASTAP when extracting green.

What seems really strange is there is a hot pixel (I think) at x = 1097.5, y = 820.5.  It is present in the AIJ green extraction but not in the ASTAP one.  I'm not sure how to tell the pixel color using AIJ.
