Example of dominant frequencies and tremor classification of each segment for patient 1.

<p>Top: identified DFs during the analysis of approximately 23 minutes of tremor data using <i>Periodogram</i> (pink), <i>High Freq</i> (purple) and Welch (2) (green). Each circle corresponds to the dominant frequency of one segment. This figure illustrates that the High Freq method was not constrained to a specific frequency resolution like the Periodogram or Welch methods. A segment was classified as “tremor” if the DF was located in the 2.5–12 Hz frequency band (pale green) for this example. Bottom: The tremor classification according to the consensus between both clinicians (black: agreement on tremor presence, white: agreement on tremor absence, red: lack of agreement), and for every automatic detection method are shown for the same dataset (tremor bandwidth = 2.5–12 Hz, power threshold = 0 m²/s⁴). The tremor classification corresponds to individual segments, before rearranging the data (as illustrated in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0156822#pone.0156822.g001" target="_blank">Fig 1</a>).
