I have a mammographic image of size 1024 x 1024, and I have the center coordinates of the anomaly (338.314) and the radius (56) in pixels of the circle containing the anomaly. I desire to extract a region of interest of size 128 * 128 including the anomaly. I tried with
rect = [338-64,314-64,127,127]; crop = imcrop (img, rect) ; but I obtien an ROI that does not contain the desired anomaly. any suggestions please.

Are you sure you're getting row, column correctly matched up with x,y? Remember x,y is column, row, NOT row, column. Try
rect = [314-64, 338-64,127,127];
and see if that fixes it.

And what about the big black block on the left edge of the image. Can you answer my question about that?
