| The Event_TPR_Signal command performs pattern recognition on a signal by scanning the trial for segments that match a **Target Pattern Recognition (TPR) file**. When a segment of the trial is sufficiently similar to the pattern, an event is placed at the frame of best match. | The Event_TPR_Signal command performs pattern recognition on a signal by scanning the trial for segments that match a **Target Pattern Recognition (TPR) file**.
