I attempted to convert the code to work with uint16 data by changing line 73 to: ('BitsPerSample', 16) īut after writing with outFileWriter = bigTiffWriter('test.tif', inFileInfo(1).Height, inFileInfo(1).Width, tileSize(1), tileSize(2)) įor b.data,'Destination',outFileWriter) Which results in the following output: Frame 10000 written in 66 seconds, 8.196721e+00 percent complete, time left=743 secondsįrame 20000 written in 225 seconds, 1.639344e+01 percent complete, time left=1145 secondsįrame 30000 written in 481 seconds, 2.459016e+01 percent complete, time left=1474 secondsįrame 40000 written in 915 seconds, 3.278689e+01 percent complete, time left=1877 secondsįrame 50000 written in 1512 seconds, 4.098361e+01 percent complete, time left=2177 secondsĪttempting to make use of the BigTIFF library does not work Tagstruct.PlanarConfiguration = ĭivider = 10^(floor(log10(numframes))-1) Notice the exponential increase in time as more frames are written.

Use imwrite to write IMG to test.tif (recommended by MATLAB documentation) tic On the same machine, MATLAB would likely take days to do so using any method I have tried. ImageJ or a short Python script can do this in less than one minute on a fast machine.
I am trying to write a single multipage tiff file which is 128 pixels x 128 pixels x 122000 frames of 16-bit unsigned integers.
