Overview

E-Prime is a software package used in behavioral psychology and functional neuroscience studies, with facilities for presenting stimuli and recording responses and their timing.

Optimus is a set of utilities to convert and process E-Prime's data files so they can be processed outside of Windows -- for example, automatically in a script.

This lacks a GUI, but it should now have enough features to process most E-Prime files into formats that will be useful for running GLMs and other regression tasks.

Most notably, this now handles:

• Converting E-Prime files from log format into tab-delimited format
• Merging multiple files into one
• Doing columnwise mathematical operations and row-wise filtering
• Generating AFNI stim_times files from E-Prime data
• Extracting column values into tab-delimited files

Version 0.6.9 released

New features:

• No longer jumbles column order of eprime log files
• Now supports Procs for starting values of computed columns
