7.1.130. 3dRank

Link to classic view

Usage: 3dRank [-prefix PREFIX] <-input DATASET1 [DATASET2 ...]>

Replaces voxel values by their rank in the set of values collected over all voxels in all input datasets If you input one dataset, the output should be identical to the -1rank option in 3dmerge

This program only works on datasets of integral storage type, and on integral valued data stored as floats.

-input DATASET1 [DATASET2 ...]: Input datasets.
Acceptable data types are: byte, short, and floats.
-prefix PREFIX: Ouput prefix.

If you have multiple datasets on input the prefix is preceded by r00., r01., etc. If no prefix is given, the default is rank.DATASET1, rank.DATASET2, etc.

In addition to the ranked volume, a rank map 1D file is created. It shows the mapping from the rank (1st column) to the integral values (2nd column) in the input dataset. Sub-brick float factors are ignored.

INPUT DATASET NAMES

This program accepts datasets that are modified on input according to the following schemes:

‘r1+orig[3..5]’ {sub-brick selector} ‘r1+orig<100..200>’ {sub-range selector} ‘r1+orig[3..5]<100..200>’ {both selectors} ‘3dcalc( -a r1+orig -b r2+orig -expr 0.5*(a+b) )’ {calculation}

For the gruesome details, see the output of ‘afni -help’.
