Hi Asif, I think you forgot to add the link, I did a Google search and found what you probably were looking at. This is a custom software developed for use with ENVI. We don't have access to that nor do we support it. There was an e-mail address of the author of that tool. You may want to contact them directly with for download details.

Yep I forgot the link. Thank you very much for your time and feedback. I have already sent an email to that address. Lets see what happens. Thanks Again.
