 The time or latency of each trial can be constructed using the sampleinfo from the segmented data, which specified for each trial the begin and the end-sample relative in the original datafile.  ​ The time or latency of each trial can be constructed using the sampleinfo from the segmented data, which specified for each trial the begin and the end-sample relative in the original datafile.  ​
