Hi all  

I am new to APP (trial).  I have Sony A7rii and therefore using 16bit TIFF files (~240MB) converted from uncompressed .ARW.  These files load into APP but I get java outofmemory errors on calibration or analyse stars, even with small numbers of subs.  I am asking at this stage whether such files should be OK in APP, before perservering further with settings. (Desktop i7, 16GB,windows 10)  (These files process OK in Nebulosity 4, but not DSS 3.4.4) 

Thanks

Peter

Hi Peter,

Thank you for your question and welcome to the APP forum 😉

The files should be okay, you only need to configure APP to use more memory than the initial configured amount of 2GB. Check this topic on how to do this:

https://www.astropixelprocessor.com/community/faq/how-much-memory-should-i-allocate-to-app/

So with your 16GB of memory and windows 10, I would set the amount of memory that APP can use to 12-15GBs. Leaving 1 -4 GBs of memory to spare to let Windows 10 function properly 😉

Your files shouldn't need more than 4GB of memory for APP to function without out of memory exceptions to occur, unless you are starting to make big mosaics. Then more memory is required.

Let me know if you can process the Tiffs fine now 😉

Sony RAW support will come by the way, working on it.

Thanks for that 😊 .  Yes, started working immediately after increasing the RAM.  Now getting to grips with your great program.  Looking forward to sony raw handling.
