Then my question is - the latency recored by software, is it the response time from 200 ms ( when target appeared for the first time ) or is it the response time from the last fame which is 300 when the target reappears again ( although it is not evident to naked eye) And the second question is about / trialdata- ( / trialdata = [primeA, target] ) in this command- will the program only record latency between primeA and target and I will not get any other columns ? Thanks Abhi

In your example, latency would thus be relative to mask. If you don't want that, you need to use the /beginresponsetime (formerly /responsetime) attribute. Details are available in the documentation.
