esm_calc: Calculate extended speed matrix from individual tracking...
In michathoma/flywalkr: Analysis tools for the flywalk behavioral paradigm

esm_calc collects the output from the tracking software and creates the extended speed matrix as a summary of a given experiment. Time of encounter with the odorant (i.e. the intersection of a tracked item and a linear model of odor travel) is determined for every item individually. After calculation of walking speed, individual speed trajectories are aligned to a common timeline. Tracking events will only be analyzed, if the timer contains neither intervals longer than 0.1s nor intervals of length 0. To account for edge effects, x-position values < 0.5 and > 19 are treated as NA

1 2	esm_calc(directory, tubeDelay, windspeed, interval, before.after, priority.interval)

`directory`	A directory containing tracking raw data.
`tubeDelay`	a `double` specifying the delay (s) between the trigger to deliver the stimulus and the odor entering the glass tube.
`windspeed`	a `double` specifying the wind speed (cm/s) inside the glasse tubes.
`interval`	a `double` specifying the desired time interval (s) between two speed datapoints, typically 0.1s.
`before.after`	a `double` specifying the time (s) before and after odor encounter to analyze.
`priority.interval`	a vector specifying the time interval (s) during which the item has to be continually tracked to be considered for further analysis.
