Over the years, I have developed various pieces of code/tricks/ to make my life a bit easier. This ranged from simple tricks in latex to make my life easier, illustrator hacks, and explicit code packages developed to analyze spiking and behavioral data. My and Our lab’s philosophy is that  we need to share more and more code and data so that we can learn from other people. Science is a collaborative endeavour and we should all be making each other’s lives easier.

CHaRTr is an attempt by us (Chand Chandrasekaran, Guy Hawkins) to provide researchers interested in various models of decision-making a simple, easily run and an extensible toolbox for analysis of RT and choice behavior in decision-making tasks. This toolbox or earlier less-documented and elaborated variants of it have currently been used in four papers (Chandrasekaran et al. 2017, Hawkins et al. 2015a, Hawkins et al. 2015b , Evans et al. 2017) and we anticipate/expect/hope that many more are going to be published based on this toolbox. The motivation to release this toolbox is for a few reasons which are documented in the respective page and also on the github repository (page), (github link).


openEyeTrack is our low cost, high speed, low latency, open-source video-based eye tracker. Commercial eye trackers are 1) often very expensive, and 2) incorporate their own proprietary software to detect the movement of the eye. Closed source solutions also limit the researcher’s ability to be fully informed regarding the ongoing processes within their experiment and incorporate modifications tailored to their needs. openEyeTrack is our effort to address this need. The code is freely available (github link)
