The software and models listed here were originally written in MATLAB 5 and Simulink 2, under Mac System 7-ish, starting in 1995(!). OMtools has been updated and tested regularly over the years, and is in daily use. It is compatible with MATLAB 2018 through 2024, and macOS 10.14 through macOS 14. (I have done some testing up through Windows 11). There are currently no show stoppers, though there may be some cosmetic issues. In some cases Simulink models may respond with a flurry of non-fatal warnings. I have tried to catch and fix these whenever possible while modifying the models for modern Simulink versions. If you wish, type "warning off" at the command line to suppress them (at your own peril!). OMtools Software: OMtools is a set of command-line and GUI functions written to aid in ocular-motor data retrieval, analysis, and display. (I also have been developing a package that can control the Eyelink tracker system developed by SR-Research, Inc, when used with the Psychophysics toolbox. This requires MATLAB/PTB programming skills to create new experiments. If interested, email me for more information.) NOTE: Some functions require the MATLAB Signal Processing Toolbox. If you have any questions, email Dr. Jacobs at jxj24 (at) case (dot) edu. OMtools 2 is here! This is a ground-up rewrite of most of OMtools. (There is nothing more humbling than reviewing your 25+ year-old code.) I have added major improvements to the data-reading functions, notably "datstat", a GUI front end to "rd" that gives greater control over preprocessing (filtering, deblinking and bias adjustment) at load time. It shows current filtering parameters, and lets you modify them without reloading the data. Additionally: --You can now import Eyelink EDF files in addition to the prior formats. --(Jan 2021) Preliminary support for calibration and analysis of vergence data. --The saccade parser, "findsaccs" has greatly improved sensitivity and selectivity, along with a GUI to make interactive examination of your data easier. --Blink removal from non-digital (i.e. non-blanked) data sources (e.g. Eyelink analog output) is likewise improved using "ao_deblink". --Post-facto data calibration using "cal" has been streamlined and simplified. --All graphics-based tools have been thoroughly modified to work smoothly with the most recent versions of MATLAB. --Zoomtool has been updated to allow multiple independent instances that can be controlled programmatically. --Far simpler, more-reliable installation process, including auto-checking for the most current version. Download OMtools v2 OMrec is an OMtools add-on toolbox that integrates with Eyelink trackers that lets you design, present and record experiments. You can create a variety of stimuli (video and external USB/serial-controlled devices) using PsychToolbox and simple text scripts. This is a test release of the version that we have been using in our lab for a few years, so it may require minor modifications to fit with your workflow. This release includes (mostly complete) documentation for getting started writing your own experiment presentation stimuli. It also includes instructions for building and programming Arduino-based interfaces to LED bars, and design specs, 3D-printing STLs, and a purchase list of components for making your own LCD shutter-based occluders if you're feeling adventurous! Download the test version of OMrec. Download the required "EL_support" toolbox.

DD_OMLAB Eye-Movement Database: Begining in 1986, most data from approximately 722 recording sesions were simultaneously taken digitally and the data files from those sessions compose a valuable storehouse of research data. These data are now being made available to all researchers, residents, fellows, and students of ocular motility along with the software tools (OMtools) necessary for their display and analysis. The data and their analysis will hopefully allow those unable to actually record the eye movements of affected individuals to test hypotheses and conduct future ocular motor research into nystagmus. Citation: Should any data from the DD_OMLAB Eye-Movement Database be used in a publication, the relevant DD_OMLAB subject numbers should be listed and the citation should contain a link to this page. All data have been de-identified in accordance with current research practices to protect the privacy of each person recorded. The digitized, de-identified human eye-movment DD_OMLAB data available for downloading from this page is divided into four parts: 1) data in published papers from 2002 - 2014; 2) all data, published and unpublished, recorded from 1986 to 2013; 3) data recorded in 1984 in the laboratory of Dr. R.M. Steinman, from S001; and 4) data recorded in 1993 in the laboratory of Dr. H. Collewijn from a human with achiasma, INS and SSN. NOTE: Digitized canine data may be found on the [COMLAB] page. For a detailed tutorial on recording and analyzing eye-movement data from subjects with nystagmus or other ocular motor disorders, see OMLAB Report #011005 (HTML) (PDF) For a detailed tutorial on the use of the NAFX, see OMLAB Report #111005 (HTML) (PDF) NOTE: NAFX is part of the OMtools distribution, available through the above link. Some programs require the MATLAB Signal Processing Toolbox. For questions regarding the use or analysis of these data, email Dr. Dell'Osso at lfd (at) case (dot) edu. NOTE: All data files are saved as zip-format archives. Beware: Many of these data files are quite large, despite having been compressed (eye-movement data is only slightly compressible). A high-speed connection is highly recommended. Those interested in obtaining the whole human eye-movement database (>1.6 GB) should contact Dr. Dell'Osso and request a DVD. Top of page 1. DD_OMLAB data in published papers (2002 - 2014) may be downloaded from each of the numbered papers listed below. The following are deidentified, downloadable copies of human subjects' digitized eye-movement data from papers published in refereed scientific journals. The criteria required for these data are: 1) all the data were collected in OMLAB; 2) our calibrated eye-movement systems were used; 3) our nystagmus paradigms were followed; and 4) the patient's privacy would not be compromised by release of the data.The subject numbers identifying each data set are consistent with those in their respective published paper. PDF's of each paper may be downloaded from (Downloadable PDF's) The 'Deidentified Human Research Data' document correlates the published S #'s with the DD_OMLAB Subject #'s, thereby allowing additional data from each published Subject # to be downloaded.
