Image integration

[blueridgeDSIA]

Hello, I am trying to integrate a stack of data and it keeps failing.  I am not sure what the proper way is to share this bug, if it is a bug.  2 days ago I registered the data with frame adaptation selected in image registration, there is a slight overlap in these two data sets.  Today I re registered all of the data without using frame adaptation to see how the integrated image would look by comparison.  For some reason the data will no longer integrate.  It does not matter if I try to use an ROI or the entire image, image integration crashes every time.  I am getting this message below. Let me know if I need to pull more info from anywhere else.

Hi, How many images are you trying to integrate? Unfortunately, some out-of-memory errors are not correctly reported on Windows, leading to these obscure 'unknown exception' errors. When this happens, most likely you are trying to integrate too many images with your available RAM resources.

Try to adjust the buffer size and stack size parameters of ImageIntegration (read the tooltips for more information). Hope this helps.

I am getting a similar problem.  I am following David Alt's example at his trappedPhotons website.  If I tell the image-integration process to do more than 24 images (I'm trying to add up bias frames) it crashes not long after the console says it's waiting for processes to terminate: the pixInsight window just vanishes.  A few times I have had it lock up my desktop.  It seems to be extremely busy at that point.  I am running on linux, if that matters. If I start pixInsght from a terminal window, I get this message when it fails:

/opt/PixInsight/bin/PixInsight.sh: line 35:  7108 Aborted                 (core dumped) /opt/PixInsight/bin/PixInsight

which is not very informative.
This has me stopped and days remaining on my trial license are ticking away.

Hi:
Only 30.  I am using Ubuntu 17.10.  My system has 8GB ram and 180 GB of free disk space, so I don't think it is resource starvation.

I tried increasing buffer size to 64 and stack size to 4096.  It crashed the same way.

Are you on a Dell laptop running Windows 10?

If you have been trying to integrate raw files from a DSLR camera directly, try the following: Convert them to xisf format first (with BatchFormatConversion script) first and then integrate the converted files.
