problem with .mat to .vtk format

I want to convert .mat files to .vtk format. Is it possible ? But how ?

In file exchanger, the code is available. Please check following link http://www.mathworks.com/matlabcentral/fileexchange/23416-writetovtk

Thank you so much for your rapid response, Pritesh. Highly appreciate it. Unfortunately, my images are 2D images (above mention code only works for 3D images) and they are saved in .mat format (after the segmmentation).

Hence, how to convert 2D .mat files to 3D .mat files. Can anyone kindly give me a clue for that so then i can use the above code.

Anyhow Pritesh, your quick response for my original question is highly admired.

Walter, thank you so much for your response. Really appreciate it.

I came up with another question which i will ask here as it is related to the original question (sorry if i caused any inconvenience).

So far i have a 2D matrix (eg:segmented masks)but i want to add the 3rd column (which is the slice thickness) to this matrix. So these masks are saved in .mat format. Is it possible for me to add a 3rd column to this matrix?

If you mean can you add it to the .mat file, then Yes: load the file, change the variable, save back to the file again.

If you mean can you add the column to what you are exporting to VTK, then I do not know.

I meant to the .mat file. That answered my qu. Thanks Walter :)

Hi, i know i am little late to write to this but unfortunately i do not get the converted vtk file using the above code (Tim's code).I know it should work, but i don't understand why i am not getting it though. Can anyone guide me to detect the problem? (ps:i am writing here coz its related to this topic).
