convert the fixation or saccade sequence to a representation in terms of relevant and irrelevant AOIs Syntax: sequence = calcIrrRelSeq( AOISequence, relAOIs ) Inputs: AOISequence: matrix (numAOI x number in sequence) with an indicator (1) for in each column corresponding to the AOI of interest. If no AOI, it will be all 0; relAOIs: index of AOIs which we are interested in Outputs: sequence: matrix ( 2 x numSeq ) where each column corresponds to an AOI visit. first row is 1 if relevant, 2nd is 1 of irrelevant, and both are 0 if no AOIs visited.
