MATLAB createOutputTable Function

This repository contains the MATLAB function createOutputTable(). This function takes the results table from the Statistical Parametric Mapping toolbox (SPM) and extracts (1) essential data (e.g., p-values, t-values, cluster size, coordinates, and hemisphere) and (2) applies the mni2atlas toolbox to each coordinate. The output is a neat table with all necessary information and brain areas from X different atlases to use for publication.

How to use:

1. Save your SPM output table to a mat file (you can find it under the struct variable TabDat that appears when a contrast is loaded in SPM's results pane)
2. run tbl = createOutputTable('PATH', 'contrastName'), where:
   • 'PATH': Path to SPM's output table (.mat file)
   • 'contrastName': Name of contrast

The function will return a structured table tbl containing the processed data. You can run this function for all the contrasts of interest and then concatenate the tables to have one big handy overview e.g. using all_results = [tbl1; tbl2; tbl3; tbl4].

Dependency:

This function needs the mni2atlas toolbox. Download it here first and add it to your MATLAB path.

Example Data

You can find an example output file ExampleContrast.mat in this repository to test the function's functionality. Simply run tbl = createOutputTable('ExampleContrast.mat', 'exampleContrast')
