mincPairedTtest: Minc Paired T Test

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

Minc Paired T Test

Description

Perform a paired t-test across a set of minc volumes

Usage

mincPairedTtest(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. The two groups must be the same length.
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

Examples

## Not run:  
getRMINCTestData() 
gf <- read.csv("/tmp/rminctestdata/minc_summary_test_data.csv") 
gf = gf[1:20,]
mptt <- mincPairedTtest(gf$jacobians_0.2,gf$Strain)

## End(Not run)
