Dear All  
  
I have recently acquired an Arrington Research eye tracker (monocular quickclamp system)   
but am having problems connecting it to PsychToolbox. Arrington Research is having   
some difficulty helping me as the relevant programmer has left the company.  
  
I understand from the company that there are many people in the vision community who   
are able to connect this eye tracker to psychtoolbox. I would very much appreciate any   
help that they can give me.  
  
I am running (successfully) the eye tracker on a Dell PC. Using an ethernet cable I can   
successfully import the data from the PC into my Mac G4 on which I am running   
Psychtoolbox V3 (in MATLAB 7.5, MacOS 10.5). However, any time I try to access this data   
using any function in the Matlab toolbox that came with the eye tracker I get the   
following error message:  
  
??? Error using ==\> calllib  
method was not found  
  
Does anyone know how to work around this problem?  
  
Many thanks  
Piers
