I can open small tif files (3 channels, 100 time frames) nicely. However, I could not open a large Tif file of 8.4 GB.

ImageJ writes its own header somewhere else, and God knows where it puts the data.\r\n\r\n> I suppose we could fall back to using `tifffile` to read the data\r\n\r\nAs far as I can tell, `tifffile` can only read the header information, not the contents. `tifffile.imread()` and `vigra.readImage()` import exactly the same data (namely the first channel of the first frame)."}}
