Memory Error

Hi

I have been using AIJ for a short while now and have just started looking at reducing data from a different telescope.  The camera on this telescope produces 32Mb image files.  When I started running the DP module I got the following message;

   Out of memory.  All available memory (567MB) has been used.

The memory value actually varies a bit each time I tried it.  I have 16Gb installed so have tried following the installation instructions increasing the memory available to both 2Gb and 4Gb but I still get the same error.  After checking on these forums for answers I have checked the amount of memory allocated and the version of Java by clicking on the bottom of the AIJ window.  It shows the following

   ImageJ 1.47i; java1.7.0_71(64bit); 141MB of 2000Mb(7%)

This looks as it should to me but for some reason I still get the memory errors at around 570MB.  I am running AIJ3.2.0 on a Windows10 PC.

Any ideas how to resolve this would be much appreciated.

Also, while I am asking, is AIJ DP able to reduce image sets where the calibration frames are a different binning (1x1) from the science frames (2x2) as this is actually what I was trying to test?

Many thanks

Mark.
