Review Detections for the Cohort

A tool to explore, clean (such as removing bad channels or renaming channels), and transpose the ‘Detailed Events Cohort Report’ to have one subject per row.

The “Detailed events cohort report” is generated by any of the Spindle detectors (Detect Spindles with A7, Detect Spindles with Martin or Detect Spindles with SUMO) or the Detect Slow Waves tool in Snooz.

Warning

The option to generate the cohort report has to be checked by the user on step “4 - Output Files” in those 2 tools.

The generated report includes the same variable names as the input report. However, in the transposed report, the channel label is concatenated to the variable name as a suffix. I.e. total_spindle_count from the spindle cohort report becomes total_spindle_count_EEG C3-OL for the channel EEG C3-OL.

Steps

1 - Input Files

Detailed Events Cohort Report :

Add your reports generated by the event detector tool. You can append more than one report.

Channel label :

The channel label is editable by double-clicking on the name. You can change the channel name at the subject level or at the cohort level. A channel label changed at the cohort level will be effective to all the subjects loaded. Uncheck a channel to remove it.

Region Of Interest :

You can add ROI at the cohort level to average many channels together. Once you press the “Add ROI” button : check the channels to include in the ROI (this list will be adapted to the cohort loaded). Check the blank option if you want the ROI empty (blank) when data is missing for the mean otherwise missing data is just ignored.

Warning

Rename your channel labels first. Adding the ROIs must be the final step.

2 - Output Files

Check the reports you want to generate:

  • the report cleaned (with edited channels)

  • the report transposed

To export the transposed report, define how to average the events characteristics across the recording by selecting :

  • Total to output the average through the whole recording.

  • Distribution per clock hour to output the average per real clock hour, from hour 1 to 9.

  • Distribution per hour spent in each sleep stage to output the average per stage when it reaches an hour, from hour 1 to 9.

  • Distribution per sleep cycle to output the average per sleep cycle, from sleep cycle 1 to 6.

Define the filename to save the exported files (the sufix _clean or _transposed will be added to the filename) The output file is a .tsv (tab separated values) file.

Warning

The current output is added (appended) to the existing output file.
