Description README – MHC biobot stimulus-response data files.
This archive consists of (sub)directories, one for each test experiment. The date on which the experiment was performed is indicated in the top level folder in YYYYMMDD form. Typically subfolders are named ROACH_. Some folders contain a further suffix such as _I or _V to denote current vs. voltage stimuli.
Folders contain data for:
• Motion tracking with 2 optical mice. Filenames are: mouse{1,2}XY_.txt. The two files are for two orthogonal mice.
• Electric stimulus pulse parameters. Filenames are: pulseparams{1,2}XY_.txt
• Experimental timing parameters (such as length of a single trial, time at which stimulus delivery begins, etc.). Filenames are: expparams{1,2}XY_.txt
Note that not all directories contain all of these file types as some were added during later experiments (generally, earlier experiments are missing expparams files).

A MATLAB code archive is included to aid analysis and visualization. There are many automated functions and scripts to process large data sets. A good point of entry is to use the GUI interface, which allows the user to quickly scan through trials for a given test subject to view linear and angular responses to a given stimulus. Type >> help roachgui.m for more information.
Core file-loading functions are:
• twomouseXY.m (loads optical mouse tracking data)
• readpulseparams.m (reads a pulse parameters file)
• readexpparams (reads information in expparams file)

Another core analysis function is roachda.m, which automates processing of linear and angular responses for all trials in a single directory.

For more information on how to use these and other function, consult the help in MATLAB, or contact Jon Erickson, ericksonj@wlu.edu
