This menu controls how data is to be input to the program. NOTE: these options ONLY applies to data when it is input. Once input the data cannot be flipped.
Display: This displays the current input options set
Flip Left/Right: This flips the data left to right on input
Flip Top/Bottom: This flips the data top to bottom (this can be convenient if the data set was generated in northern hemisphere coordinates but is actually on southern hemisphere coordinates)
