Purpose:

Interpolates the input image file to cubic voxels and optionally saves a .air file describing this transformation.

Usage:

zoomer input output [options ]

options:

[-f output-air-file-name [overwrite?(y/n)]]

saves a .air file describing the transformation

[-o]

grants permission to overwrite output

[-s]

suppresses generation of output when -f option is used

where the following definitions apply:

input

the name of the input file

output

the name of the output file

output-air-file-name

the name of the .air file to create

overwrite?(y/n)

'y' grants permission to overwrite output-air-file-name

Examples:

• If the x, y and z voxel sizes of file mri are not identical, file mri will be interpolated to generate a file with cubic voxels called interpolatedmri. The voxel sizes in file interpolatedmri 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 mri are all identical, file interpolatedmri will be identical to file mri.

• A .air file called mri.airinterpolated will be created with mri as the reslice file and interpolatedmri as the standard file describing the interpolation identical to that in the example above. No new image file will be created because the -s flag is used.

Comments:

• This program uses trilinear interpolation. If you want a different interpolation model, use the -f option to create a .air file and then use reslice to apply the interpolation model of your choice.
• AIR 3.0 used a different syntax in which a 'y' after output would grant permission to overwrite output. This syntax is still supported so long as no optional arguments are used, but this older style syntax should be avoided in new scripts and may not be supported in the future.

Error messages: (alphabetical by case)

Cannot parse argument ____

• chech syntax

If you use the -s flag with zoomer, you must use the -f flag

• supply -f and its argument or don't use -s

argument -f should have been followed by a file name

• supply the required file name

arguments to ____ cannot intermix old and new style syntax

• the use of 'y' after output is only allowed if no other optional arguments are used

unable to parse argument ____ which should have started with a '-'

• check syntax
