I have a text file with data from a person who did an experiment. It is attached here. I need to get a vector with the number of every trial. Then I need a cell array that contains all the buttons pressed in that trial, all the timePresses and all the durations. E.g. for that file the trial numbers vector would be : [1 2 7 8 9]. For trial 1 the button would contain: 2 1 2 1, the timePress would contain: 5.6497, 6.6892, 12.3369, 12.7852 and the duration would contain: 0.8395 5.6476 0.4483 6.1118. I imagine we need something like textscan or regular expressions but I don't really know how to use them... Thanks on advance for every advice.
