# Export external data

Aim

To export data like physiological data that were imported into EthoVision XT, to another application for further analysis. You can export the original data or the resampled data.

To export the original external data:

1.Choose Analysis > Export > Raw Data.

2.Select External data log (non resampled).

3.Choose the File type and click Start Export.

Notes

▪Each line in the exported data file represents one sample according to the original sample rate. For example, for Heartbeat sampled at 1 sample/s:

▪Trial time and Recording time are the original time stamps relative to the start of the trial and the start of the track, respectively.

▪For text export: each file contains the original signal combined with the current Data profile/Result container. The default file name is:
External-[experiment name]-[Trial number]-[signal name]-[Data profile or Result container name]-[Arena name]-[Subject name].txt.

▪For Excel export: each file contains the signal from one trial. The default file name is:

Raw data-[experiment name]-[Trial number].xlsx.

Within an Excel file, each sheet contains the signal combined with the current Data profile/Result container. Sheets are named in this way: [signal name]-[Data profile or Result container name]-[Arena name]-[Subject name]. This name may be truncated.

▪For more information on other options, see Export the raw data (track and dependent variables).

To export the resampled external data:

1.Choose Analysis > Export > Raw Data.

2.Select Track and dependent variables.

3.From the list on the toolbar, select the Analysis profile that contains the resampled signals. See External data (resampled)

4.Choose the File type and click Start Export.

▪In the exported data file, each line is one EthoVision XT sample. Each resampled signal is written in a column. The Data profile column indicates whether a sample is included (1) or not (o) in the Data profile.

▪Export files are named like Raw data files. For more information on other options, see Export the raw data (track and dependent variables).

▪To export a specific selection of resampled external data, first edit the Data profile.

To export the signal statistics

Make sure that the signal is selected in the Analysis profile, with the Trial Statistics that you require. Next, choose Analysis > Export > Statistics. See Export the statistics result
