zoomer

Purpose:

Interpolates the input image file so that the corresponding output file will have cubic voxels.

zoomerinput output [overwrite?(y/n)]

where the following definitions apply:
input name of the input file (.hdr or .img suffix optional) output name of the output file (.hdr or .img suffix optional) overwrite?(y/n) the letter 'y' if you want to allow a preexisting file with the nameoutput to be overwritten

zoomer pet1 pet2

If the x, y and z voxel sizes of file pet1 are not identical, file pet1 will be interpolated to generate a file with cubic voxels called pet2. The voxel sizes in file pet2 will be equal to the smallest of the x, y or z voxel input sizes.
If the x, y and z voxel sizes of file pet1 are all identical, file pet2 will be identical to file pet1.

This program uses trilinear interpolation. If you want to use some other type of interpolation, you should use manualreslice to specify a .air file that will perform the equivalent interpolation. Be sure to specify all rotations and translations as zero and all rescalings as 1. Also be sure to use the option to generate a .air file with top-to-top alignment rather than center-to-center alignment. If this option is not offered, you will not be able to interpolate correctly.
