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 worked well -- is now dated.  Apple 'depreciated' Carbon some time ago and removed it entirely after the 'Mojave' update to MacOS (OS 10.14).  Therefore, legacy Carbon-based Warthog apps no longer function on MacOS 10.15 ('Catalina').
      I have upgraded LabAnalyst to 64-bits and it does run on 'Catalina' but has not been exhaustively tested.   So it 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 bugs (chappell@ucr.edu ).   It is not known to work with OS versions earlier than 10.11.
      LabHelper has also been converted to 64-bits 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 appreciate feedback if you try it (downloads page).   It will work in 'Catalina' as long as the necessary software driver update for the USB-serial interface is installed from this website - you want the 'USA-19HS Driver (Mac os X 10.12 to 10.15.x)' .

IMPORTANT:   On new machines that come with MacOS Big Sur, or later MacOS (e.g., 'Monterey'), the Warthog apps will NOT run successfully (although they may launch).   Also (alas), new machines probably will not allow installation of earlier MacOS versions that successfully host Warthog software -- M1 Macs certainly won't.

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 worked on ecological and evolutionary aspects of animal physiology).  The programs are 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, other things may take precedence.
