Read a TIFF stack as a memory-mapped tensor. Handles a large range of internal TIFF formats.

Description

If this code is useful to your academic work, please cite the publication in lieu of thanks:
Muir and Kampa, "FocusStack and StimServer: A new open source MATLAB toolchain for visual stimulation and analysis of two-photon calcium neuronal imaging data". Frontiers in Neuroinformatics (accepted).
Usage: tsStack = TIFFStack(strFilename <, bInvert>)
A TIFFStack object behaves like a read-only memory mapped TIF file. The entire image stack is treated as a matlab tensor. Each frame of the file must have the same dimensions. Reading the image data is optimised to the extent possible; the header information is only read once.
  
This class attempts to use the version of tifflib built-in to recent versions of Matlab, if available. Otherwise this class uses a modified version of tiffread [1, 2] to read data. Code is included (but disabled) to use the matlab imread function, but imread returns invalid data for some TIFF formats.
permute, ipermute and transpose are now transparantly supported. Note that to read a pixel, the entire frame containing that pixel is read. So reading a Z-slice of the stack will read in the entire stack.
Construction:
>> tsStack = TIFFStack('test.tiff'); % Construct a TIFF stack associated with a file
>> tsStack = TIFFStack('test.tiff', true); % Indicate that the image data should be inverted
tsStack =
  TIFFStack handle
  Properties:
         bInvert: 0
     strFilename: [1x9 char]
      sImageInfo: [5x1 struct]
    strDataClass: 'uint16'
Usage:
>> tsStack(:, :, 3); % Retrieve the 3rd frame of the stack, all planes
>> tsStack(:, :, 1, 3); % Retrieve the 3rd plane of the 1st frame
>> size(tsStack) % Find the size of the stack (rows, cols, frames, planes per pixel)
ans =
   128 128 5 1
>> tsStack(4); % Linear indexing is supported
>> tsStack.bInvert = true; % Turn on data inversion

Hi David, thanks for your message. I'm sorry about that regression. I've uploaded a new version which fixes the problem.
Best regards, Dylan,

With the most recent version getting errors when accessing object properties like strDataClass

Error using cellfun
Input #2 expected to be a cell array, was char instead.

Error in TIFFStack/subsref (line 289)
cellfun(@isvalidsubscript, S.subs);

Hi Jana, the class has documentation available if you type `help TIFFStack`. What seems to be the problem?

Can't get this to work. Is there a documentation on how to use it?

Best way, to my knowledge, to work with TIFF stacks on Matlab. Recommended.
