Matlab仅打开多页tiff堆栈的第一帧 [英] Matlab only opens first frame of multi-page tiff stack

问题描述

我已经在ImageJ中创建了一个带有宏的多页tiff文件，现在我正尝试使用matlab打开它，但我只能访问第一帧.

I've created multi-page tiff files with a macro in ImageJ, and I'm now trying to open it using matlab, but I can only access the first frame.

这是imfinfo(filename)的结果.因此，我得到

Here is the result of imfinfo(filename). Accordingly, I get

length(imfinfo(filename)) = 1

Filename: [1x129 char]
              FileModDate: '28-nov-2013 12:27:51'

                   Height: 512

                TileWidth: []
               TileLength: []
              TileOffsets: []
           TileByteCounts: []
              Orientation: 1
                FillOrder: 1
         GrayResponseUnit: 0.0100
           MaxSampleValue: 255
           MinSampleValue: 0
             Thresholding: 1
                   Offset: 8
         ImageDescription: 'ImageJ=1.47q
 images=25900
 slices=25900
 loop=false

但是，如果我在ImageJ中打开相同的tif文件，则可以读取和滚动25900帧...奇怪的是，matlab可以读取我在imageJ中创建的先前的多页tiff，而无需我的批处理宏...

However if I open the same tif file in ImageJ, then I can read and scroll through the 25900 frames...The weird thing is that matlab can read previous multipage tiff I had created in imageJ without my batch macro...

我不知道发生了什么...任何帮助将不胜感激！ 谢谢， 史蒂文

I don't understand what's happening...any help would be greatly appreciated ! Thanks, Steven

推荐答案

这实际上是ImageJ的错误.对于大型TIFF，ImageJ而不是使用BigTiff标准保存堆栈，而是使用带有包含第一帧的假TIFF头保存原始文件，并愉快地将其命名为.tif.您可以与ImageJ开发人员讨论为什么他们认为这是个好主意.

This is actually ImageJ's fault. For large TIFFs, instead of using the BigTiff standard to save the stack, ImageJ instead saves a raw file with a fake TIFF header containing the first frame, and happily names it .tif. You can discuss with the ImageJ developers why they think this is a good idea.

要将这些堆栈读入Matlab，可以使用memmapfile或 MappedTensor

To read these stacks into Matlab, you can use memmapfile or MappedTensor.
