# csv outputs

The Analyzer csv outputs for each pipeline contains some columns which are the same as in the raw data exported from EmotivPRO. This is detailed in the EmotivPRO manual.

In addition to these, the Analyzer outputs will include different columns depending on the pipeline.

**Basic EEG Processing:**

Key | Value |
---|---|

latency__desc | Time since the start of the recording in seconds |

eeg.<sensor> Examples: eeg.af3, eeg.f7 | Processed EEG data for each EEG sensor, in microvolts. |

sq.sampleratequality sq.overallsensorquality sq.pm sq.signalmagnitudequality sq.internalsignalmagnitudequality sq.sensorqualityscore sq.internalsensorqualityscore sq.likelihood sq.rms | These columns are for internal use for calculating EEG Quality |

**EEG transformation and Band Power Reports (Individual and Grouped) :**

Key | Value |
---|---|

stamp_i__desc | timestamp of the start of the Fourier transform window |

stamp_f__desc | timestamp of the end of the Fourier transform window |

latency_i__desc | time of the beginning of the Fourier transform window relative to the beginning of the recording |

latency_f__desc | time of the beginning of the Fourier transform window relative to the end of the recording. |

eeg.[ch]_[low_f]_[high_f]Hz__feat | The bandpowers in decibels (ie 10*log10 (band_power per hertz) in the channel ch in the band from low_f to high_f (including low_f and excluding high_f) |

minimum_cq__desc | Contact quality score of the worst channel in the Fourier transform window |

maximum_rms__desc | The largest root mean square(RMS) over the Fourier transform window. |

data_fixed__desc | A flag to say that there was data missing or other problem in the Fourier transform window. |
