Minc Paired T Test

Source: R/minc_voxel_statistics.R

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

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)
# }
