Hi Bill,

Are you using * and ? wildcard characters in your raw image filename specifier? All of the files need to match the characters in the filename specification, except for the locations of the wildcard characters.

Since you have a 64 bit OS, I assume you have much more memory than 640 MB. I would allocate about 70% of your physical memory to AIJ (see installation instructions). AIJ only uses what it needs up to the maximum you set.

Hi all,    I think my problem is similar to that of Antonio's

I'm currently trying to build a master bias and master dark set.
Strange thing is, it seems to be working BUT will only register 1
Bias out of 25...the totals counter on the right shows 1.  

CCD Data Processor:
All is unchecked on the DP panel except,  Build and ave on the
bias subtraction...this is the one I'm trying first. I have the directory
Set and the Filename/Pattern looking into the bias frame folder.
I also have the destination set...mbias.fit

Memory allocated to AIJ:
'Imagej 1.47i java 1.7.0_71 64-bit  36mb of 640mb (5%)'

My bias frames are 8.2mb...X 25!  

OS is windows 10,  I originally loaded AIJ on my computer to
See if I may have better results, I now have it on a thumb drive!!

Thanks:)
