I was just trying to collect some information from a tif stack file to know how many frames there are in this specific tif file named test. However there is some error I never encountered before and I can't find an answer online. so I post it here hope someone can answer it for me. Or can help me find another way to get the frame number information. When I was trying to open the same file with image processing toolbox it also encountered the same error. My image processing toolbox can open other jpg files.
Here's my test code and error.
>> t=imfinfo('test.tif')
??? Unexpected Standard exception from MEX file. What() is:invalid string position
Error in ==> imtifinfo at 57 raw_tags = tifftagsread ( filename );
Error in ==> imfinfo at 178 info = feval(fmt_s.info, filename);

It's possible that this is the bug referenced by http://www.mathworks.com/support/bugreports/737970
Can you post your image somewhere for me to take a look at it?

Thanks, I'm trying to upgrade the matlab to the latest version which the problem is said to be solved. The bug description is very similar to what I see. The file itself is taken by a CCD software and the stack image is very large. I'm trying to think of a way to share it.

Thank you John. The bug was fixed in ver. 2011b and I just upgraded to it. It works perfect now.

I suspect the Tags of the TIFF image are not formed correctly.

That's also my suspect but the image stacks are created directly by a CCD device and I'm not familiar with the tiff images.
