# vbtmap(1)

create a t-statistic map for VLSM

## NAME

vbtmap - create a t-statistic map for VLSM

## SYNOPSIS

**vbtmap** \<lesionfile\> \<scorefile\> \<outfile\> \<flag\> ...

## DESCRIPTION

**vbtmap** is part of the VoxBo suite of tools for brain image analysis.

**vbtmap** takes as input: a 4D lesion file containing 0/1 lesion maps for a series of subjects; and a 1D file containing a score for each subject. It carries out a separate t-test for each voxel comparing the scores of those subjects with a lesion in that voxel with the remaining subjects. **vbtmap** can optionally calculate a Welch's t-test, and can calculate FDR-controlling thresholds.

To get a complete list of available flags, run the program with no arguments.

## AVAILABILITY

Pre-built VoxBo binaries are available for Linux, OSX, and Cygwin, and via the NeuroDebian project (neuro.debian.net) for Debian derivatives.
