mincWilcoxon: Minc Wilcoxon

In Mouse-Imaging-Centre/RMINC: Statistical Tools for Medical Imaging NetCDF (MINC) Files

Minc Wilcoxon

Description

Perform a Mann-Whitney U test between a set of minc volumes.

Usage

mincWilcoxon(filenames, grouping, mask = NULL, maskval = NULL)

Arguments

filenames	Filenames of the MINC volumes across which to run the test
grouping	Contains same number of elements as filenames; must contain exactly two groups.
mask	A mask specifying which voxels are to be included in the test
maskval	The value with which to mask the data (data will masked +/- 0.5 around this value

Value

The output will be a single vector containing as many elements as there are voxels in the input files, with that voxel's U value (lower one). The number of observations in each sample is also saved as an attribute(m and n) so the result can be passed into mincFDR.
