1. Introduction

The BrainSuite Statistics Toolbox in R (bstr) is a software package developed in R that performs statistical analysis of population-level neuroimaging data processed using BrainSuite. It provides statistical tools for conducting cortical thickness analysis, tensor based morphometry, and analysis of diffusion measures.

Bstr is cross-platform and is available on macOS, Windows,and Linux based systems (all platforms with R support). bstr is distributed under an open source license (GPLv2-only). It supports functionality for automated report generation to visualize statistical results using R-shiny and R markdown. The volumetric analysis report contains the cluster table, visualizations of clusters on image slices, and shows both the unadjusted and the adjusted versions of p-values and t statistics, respectively. The ROI analysis report shows the demographic spreadsheet, automatic bar plots for ANOVA and regressions, and scatter plot for correlation analyses. bstr also exports an R markdown report that contains reproducible R commands in both the Rmd file and in the html document. This enables complete reproducibility of statistical results and only requires packaging the R markdown file along with the data.
