Hi, I performed image registration of two images using the function cpselect where I selected some points on the fixed and moving images and later transformed them. Any idea on how I can locate the specific points on the moving image which can later be transformed into the fixed imag?

Assuming the transform type you're using supports it, you would use transformPointsInverse.

You can use datatip() instead of ginput, although youwill have to set SnapToDataVertex appropriately, if you want to be able to select non-integer pixel locations.
