Essentially, Flip allows you to view your dataset from the "side" - so that what once Z axis (the axis perpendicular to the screen when an image is viewed) will now fall in the plane of the screen. Be cautious in how you visually interpret the results of Flip. You are most often looking at data where the size of the pixels in the X dimension and the Y dimension are equal. The Z pixel size (section spacing) is often quite different different from X and Y, but in a flipped view the pixels are still represented as square, so the aspect ratio will not be 1-to-1. To obtain a 1-to-1 aspect ratio, use Resample2D and adjust the magnification on the X or Y axis to equate the X and Y pixel spacings.

Use this menu to select the orientation of the output. The names of the selection indicate which of the axes in the input will fall along the X and Y axes of the output. With X-Z Sections, for instance, the old X axis will run along the new X axis and the old Z axis will run along the new Y axis.

At a minimum, Flip keeps at least one output section in memory, and it will keep more if the total amount of memory used is less than the value, in units of megabytes, shown in the "Working space" field. You can adjust the amount of memory Flip uses by changing the value in the "Working space" field. Using more memory (provided that it is not already in use for other processes) will generally speed up the process for yz or zy flipping operations. For xz flipping operations, determining the optimal amount of memory to use is more difficult. If the data set to be flipped is much bigger than the physical memory available (in other words, Flip will not be able to make effective use of the operating system's caches), telling Flip to use more memory will usually speed up the flipping operation. If the data set to be flipped is small enough to fit in the physical memory available, entering zero in the "Working space" field will usually be the optimal strategy.

Flip accepts the command-line arguments described in Region.html. To set the desired orientation of the output from the command line, include one of the following options:
-xz-yz-zyTo set the working space, include
-maxmem=n
in the options where you would replace n with the desired amount of memory to use in megabytes. If you do not set the size of the working space from the command line, Flip will use the 64 megabytes (or at least enough space for one output section if an output section is bigger than 64 megabytes).
As an example, the following command interchanges the y and z axes of recon.xzyw and puts the result in recon.xyzw:
Flip recon.xzyw recon.xyzw
