To manually import FaceReader data and videos into The Observer XT.

Procedure

Carry out the following steps

1. Export FaceReader log files

Export FaceReader Log Files

In FaceReader, choose File > Export > [one of the options], to export the data for a single analysis, single participant, or entire project.

Under Export to text files (.txt) choose Save Detailed log. The Detailed log file contains the intensities of the facial expressions per sample and other data that you have selected under Settings > Data Export.

Important Select Include file header and Include column headers. If you do not select both check boxes, import into The Observer XT fails.

Under Export to The Observer XT (.odx), choose Save The Observer XT log. Do not select the Include detailed values checkbox. Select Save all analyses to single The Observer XT log to export one log file with the data of all the participants in the project. The Observer XT log file lists the dominant facial expressions during the tests.

Procedure

Carry out the following steps:

• Import the Observer XT log files plus videos into The Observer XT
• Import the detailed logs as external data

Import The Observer XT Log Files Plus Videos Into The Observer XT

1. Start The Observer XT, open the appropriate project or create a new one. Choose File > Import > Observational Data.
2. In the Files of type field, select The Observer XT (*.odx) from the list.
3. Browse to your Observer log file and open it. The log files are by default in the folder:

This imports the FaceReader analysis together with the video of the test participant's face.

Import The Detailed Logs As External Data

To import FaceReader data as external data, your license for The Observer XT must include the External Data Module. To see if you have this module, open The Observer XT and choose Help > About The Observer XT > License info.
