Please post your code and the error you are getting.

So use the other versions which are working. At 6 years old, it's about time you upgraded anyway. Are the other versions newer or older or both?

I need it to be executed in R2008a only. But, thanks for your response. I got it.

You say you got it. What was the issue that prevented it from running in R2008a but it ran fine in all other versions you tried?

[NagaPavani]

I don't know. But before using regionprops i used the function bwlabel() on my image. Then it worked well.

It ran in all other versions.

There was a change, starting with R2008b I believe, where regionprops could take a binary image directly and did the labeling internally . R2008b was also the first version where you could pas sin a graylevel image. Perhaps you were using code designed for a more modern version. Like all functions, if new features are added, then they are not available in older versions. Was R2008a the oldest of the version you tried? If you want to show your line of code that calls regionprops I could look at it.
