Thanks for help

Select first image ROI

   [B1 x y] = roipoly(I1);

Use selected ROI on another image

   B2 = roipoly(I2, x, y);

When you're "done" with the rectangle you can right click inside it and select create mask. I think you can also double click inside it to "finish" it.

Alternatively you can use the rbbox() function if you think that's easier. Or if it's not a rectangle, but a polygon, you can use roipolyold().
