There is a bug with CMF reg ROI registration method. I found this in the stable version as well as the nightly build. This is from the nightly build.

Landmarks ROI does change dynamically and is kept at a fixed value. Can some one please tell me how to fix this ? ROI is stuck at 10.

I did get rid of the all the configurations files and started with fresh install. (i am using Linux)
