Details

This function works with a DNA alignment (freshly) plotted on an interactive graphical device (i.e., not a file) with image. After calling alex, the user clicks twice defining a rectangle in the alignment, then this portion of the alignment is extacted and plotted on a new window. The user can click as many times on the alignment. The process is stopped by a right-click. If the user clicks twice outside the alignment, a message ``Try again!'' is printed.

Each time alex is called, the alignment is plotted on a new window without closing or deleting those possibly already plotted.

In all cases, the device where x is plotted is the active window after the operation. It should not be closed during the whole process.
