Independent variables

Aim

To assign labels to recordings and facilitate group analysis.

note  UltraVox XT does not select or group your recordings based on the labels under Independent Variable. Instead, use the independent variables in the exported data to filter recordings or group recordings in other software such as Excel or R.

Procedure

1.Choose Acquisition > Recording List. See The Recording List

2.Locate the Independent Variable column.

By default, the Independent Variables column is empty, unless you have imported the audio files; in that case the column shows the audio file name.

An independent variable is any variable that is supposed not to vary during a recording, and which you can use to label recordings.

For example, enter the value control or treated in each recording row.

Other examples:

nPhenotype (with possible values Young or Aged)

nDrug dose injected (with possible values 0.01, 0.05 mg/kg etc.).

nIf you want to combine two or more independent variables, like Day and Treatment level, include the information on both variables in the single values. For example, assign a recording one of the values Control-d1, Control-d2, Treated-d1, Treated-d2 etc.

Notes

nIf you add text under Independent Variable, the name of the corresponding UVD file and that of the UVC file are updated automatically.

nWhen exporting the call statistics, that value is exported together with the statistics for the corresponding recording.

nIf you imported an audio (UVD, WAV) file, the file name is automatically entered as independent variable for that recording. To edit this name, double-click the corresponding cell.
