Because the use of resampled data is essential for many numeric and statistical analysis methods of timeline data, emoTouch calculates an initial Resampling data set with a 100 ms time interval (10 Hz) after a realisation has been finished. The Raw data itself is safely stored as well and will never be changed. If the initial 10 Hz resampling doesn’t match your needs, you may calculate other resamplings with different sample rates in the ‚Realisations‘ section (Tab ‚Resamplings’). These new resamplings will always be calculated from the Raw data. But keep in mind that choosing a very small resampling interval might need a lot of time to calculate and might produce a very large data set with a lot of redundant information. So it’s a good idea to carefully think over which time resolution is REALLY needed and useful for the specific project.

(Note: The calculation of resamplings is currently not yet possible for playback projects, as the sessions can take place at completely different times and must first be synchronised to the media stimulus. The function will be implemented in a later version)
