I am working with the segment-editor module in Slicer 4.10.1 for Linux on a Dell Precision T7400, Intel Xeon E5440 2.83GH, 32Gb RAM
I am sharing the seg.nrrd. file back and forth over Dropbox with a collaborator who segments on laptop that uses Windows 10 Pro, Intel Core i7-8550U 1.8 GHz, 16Gb RAM.
The process started well, but the segmentation file has grown to 12.2 Mb and processes very slowly. For example, from the moment when I press the enter key after drawing a segment to the moment the segment fills in takes from 30 to 90 seconds. Other processes such as scrolling through the slices are also slowed down. Using the paint tool is less slow but still dramatically slower than before. Saving the segmentation file takes several minutes and occasionally crashes my computer.
Starting a new segmentation file with the same image moves much more quickly.
My collaborator’s laptop has no issues with the same file, and only experiences a ~4 second delay between pressing enter and the segmentation filling in.
I have tried 4.10.1 on several other computers including an iMac and a Surface Pro. I have also tried the most recent nightly build, but all have similar speeds.
Is the issue with my segmentation file, and is there a way I can clean it up to run faster?
