Zeiss confocal microscopes output data in LSM files, a stacked TIFF image format with some additional headers and info directories. See http://en.wikipedia.org/wiki/LSM_(Zeiss) for details. The functions included here will allow you to read the additional info, for example useful fields such as the pixel dimensions of the stack. I have based the current version heavily on the open source code from the LSM Toolbox plugin for ImageJ (http://imagejdocu.tudor.lu/Members/ppirrotte/lsmtoolbox).
This toolbox does not read the actual image data from the file, for that you could simply export the images into simpler formats and then use IMREAD to import the data to MATLAB. There are also now versions of tiffread or other programs out there that can read the image data directly.
See comments for additional suggestions. Note also that if you have the .mdb file output by Zeiss, this is readable in Microsoft Access and includes much of the information available here.
MATLAB 6.5 (R13)
Included is both the LSM toolbox, and my CStruct toolbox, which provides generalized methods for reading structured data from files. CStruct is required by LSM. Not the same as the other CStruct toolbox available on FileExchange!
Hi Arthur, I did a time series scan, with a marker using trigger in 1, and I could not find any variable that provide me the time at which this events happened (markers). would you tell me if there is a vector or cell that provides this information?
To read in the CLSM slice directly into MatLab download m-file called tiffread.m
Google search it or get the m-code here:

very nice tool to get all info of lsm data
lsminfo spends most of its time with imfinfo, can be commented out..

wait I should supply a link for tiffread
thanks Peter Li!

Very useful for me. Saves me some headaches of making text files for matlab to read.
I want to let yalls know that some folks wrote 'tiffread.m' and the 4th version of it can read images, but make sure that your lsm files are saved with no palette.

Trying to fix hyperlink, clarifying that CStruct is required.

Information about other code that can be used in conjunction with my work.

More fields are now read. Outputs are simplified: a single struct is returned with additional data in substructs. Despite changes, should remain be backward compatible except for very unusual cases, covered in the file comments.
