the raw voltage from eyelink is splited in two, one for monkeylogic, one for Plexon. However, I am not sure how to convert the eye voltage in Plexon to the visual degree. Using (voltage - offset) * gain, while, the converted data is not the same as the data recorded by monkeylogic?

If you are using the origin gain method on monkeylogic, that equation should work. I use Blackrock, which records signals in some odd unit which needs to be converted to millivolts by multiplying by 5/32764. You may have a similar requirement. if these aren't lining up well, you're probably not turning on monkeyLogic and plexon at the same time. You should reference eventmarkers, if they exist on both, to line up signals. For example looking for the 1st "9" time stamp on each machine.
