[Insight-users] How to set the registration region

[Brandon Lin]

Is there a way to create a non-rectangular shaped region?  Or is there a way
to perform registration with some pixel locations masked out?

I would like perform registration between two images, but there are some
pixels at the top left and top right corners I need to mask out.  If I use
rectangular region, I will have to give up columns or rows of pixels, which
is not preferred.  Any thoughts or feedback are appreciated.  Thanks.

Regards,
Brandon
