I cannot get IccProfile to work in Windows 2000. I have tried the   
Example in the IccProfile.m comments, but iccprofile() never returns   
any output.   
  

> \>\> file=iccprofile('filename',0)

Warning: One or more output arguments not assigned during call   
to 'iccprofile'.  

> \>\> icc=iccprofile('read',file) % won't work because iccprofile does

not return anything to file variable  
  
Also, I have another question about Icc profiles. If I use a   
calibration device to generate an ICC for my monitor, and use that   
ICC in my display settings in Windows, then is there any need for the   
calibration tools in the PsychToolbox? The calibration is   
automatically handled by the OS and ICC profile, correct?  
  
 Thanks,
