the question is what the limitation in your system is. You say, "Fiji is not able to process it" - why?
Do you have a 64bit processing system on your computer? this is "advantageous", or, I would say, a prerequisite. (in some way, a 32bit-operating Windows system prevents the PC from knowing what "4GB" really means; it ends somewhere at 3.3 GB or so). Some time ago, we stopped working with 32bit-operating systems - too many limitations. Second, did you "tell" Fiji that your computer in fact has 8GB RAM, i.e. how much of this memory is Fiji able to use? there is a feature in ImageJ where you have to explicitly allow the program to use a suitable amount of memory: -Edit -Options -Memory&Threads --> here, the "maximum memory" needs to be set appropriately. - Finally, but this is not essential: usually, the integrated graphic cores on mother boards are ok for the daily work with office-like programs, but not as good as dedicated graphic cards from third parties.
Here, my knowledge ends, and you might have to consult the real ImageJ and Fiji experts ...
kind regards,
Reinhard
