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

Minc T-test

Description

Perform an unpaired,unequal variance t-test across a set of minc volumes

Usage

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

Arguments

filenames	Filenames of the MINC volumes across which to run the t-test
grouping	Contains same number of elements as filenames; must contain exactly two groups with which to compare means
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 t-statistic
