ReduceRes

Overview

This application creates a new dataset which is a reduced resolution version (multiple pixels in the original are averaged to obtain a single pixel in the output) of another dataset. The factors by which the resolution is reduced must be positive integers, but they can be different for the x, y, and z dimensions.

ReduceRes accepts the command-line arguments described in Region.html. In addition, it accepts the following option:

-factor=xf:yf:zf
Sets the x sampling factor to be xf, the y sampling factor to be yf, and the z sampling factor to be zf. If not specified, a sampling factor of 2 in each dimension is used.

As an example, the following command downsamples tilts.dat by a factor of 2 in x and y and puts the result in tilts_2.dat:

    ResDown tilts.dat tilts_2.dat -factor=2:2:1
