I am using Pixel Classification in Ilastik to export for segmentation in Cell Profiler. We recently began taking larger images, and I was working with an image in Ilastik that was about 500 x 9000 pixels. I am working on a laptop in Windows 10 with 64GB RAM. When I tried to export probabilities as a tiff sequence, as we usually do, I received an error that there was not enough RAM to export to the selected format (it only worked when I cropped the image to a lower size). There were no other significant programs running in the background, and only about 10% of memory was being used. However, when I tried to export the exact same file on my personal 2011 Macbook Pro with only 16GB RAM, it was able to export the entire file.
This problem remained in both Ilastik 1.3.2 and 1.3.0 after reinstallation. I was wondering if there is some issue with a Mac vs PC in terms of how RAM is allocated to Ilastik, or if there is any way to allocate more RAM to Ilastik or some other solution to this problem.
