Why don't you try R instead?

Arvis Sulovari

I would highly recommend using R. I believe the ROC function is in the Epi package. You can read more about it here: http://www.unc.edu/courses/2006spring/ecol/145/001/docs/lectures/lecture39.htm#ROCR

Hemalatha Nambisan

Thanx both.

Chaurasia Sandeep

Use matlab, it will clear all aspects of ROC refinement over training cycle.
