LabHelper is a data acquisition program that can use several kinds of A-D converters

LabAnalyst is a powerful, versatile, and easy to use graphical analysis program

 Note to Warthog users:   The original Warthog software was based on the 32-bit 'Carbon' user interface, which -- although it works well -- is quite dated.  Apple has 'depreciated' Carbon and it will be removed entirely after the 'Mojave' update to MacOS (OS 10.14).  Therefore, legacy Carbon-based Warthog apps will no longer function on OS 10.15 ('Catalina').
      I have upgraded LabAnalyst to the modern 64-bit 'Cocoa' interface, which should function beyond 'Mojave' and does run on 'Catalina' (although not rigorously tested yet).   It works well overall but may be a little buggy in spots (downloads page).   If you are running macOS versions from 10.11 ('El Capitan') up to 'Mojave,' please use this version, and please report any bugs or other issues ( chappell@ucr.edu ).   It is not known to work with OS versions earlier than 10.11.
      Conversion of LabHelper to 64-bits is essentially complete but a few features have not been implemented and additional testing is needed.   I'm reasonably confident it will work well (it functions reliably with several A-D converters in my lab ) and would greatly appreciate feedback if you want to try it (downloads page).   It will launch and run in maxOS 10.15 'Catalina' but at this time the necessary software driver for the USB -serial interface to A-D converters is not 64-bit compliant.   Therefore, if you want to be absolutely sure of running Warthog (especially LabHelper) into the future, think about maintaining a Mac that supports High Sierra, Mojave, or an earlier OS (10.5 - 10.14).   Presumably, new machines after late 2019 will NOT run earlier OS versions.

A short 'corporate history'

"Warthog Systems" is a set of programs for acquiring, manipulating, and analyzing data from laboratory instruments.  The software was developed as part of my job in the Department of Evolution, Ecology, and Organismal Biology at the University of California, RiversideWarthog evolved largely to make life in the research laboratory easier for myself and my students (my lab works on ecological and evolutionary aspects of animal physiology).  The programs are also used by a number of colleagues around the world, and many features stem from their requests or suggestions -- so if you try the software, feedback is welcome.

I started the project in 1989 because there wasn't any commercial software that matched my needs.  I wanted something for the Macintosh that was adaptable to a wide range of measurements, able to handle different kinds of analog to digital converters, easy to use but capable of sophisticated analysis (especially for physiological research), and inexpensive.

This last feature (low cost) is a particular virtue of Warthog: since it was developed under the auspices of my UC job, the software is technically the property of the Regents of the University of California.  UC is a public-service institution (more or less), so I can provide Warthog as freeware.  If you want to perform data acquisition you'll have to buy the hardware (A to D converter, etc.), but even so, Warthog is a bargain.  The downside is that I can't provide the level of support you should expect from a commercial firm.  There are no guarantees or warranties, and while I'll do my best to answer questions and help troubleshoot, my real job takes precedence.
