Back up an experiment
Aim
To keep a safe copy of your data, or transfer an experiment to a different computer.
Prerequisites
▪The second computer must have EthoVision XT installed, with a version equal or more recent than that in the first computer.
▪Note that the hardware key is necessary to acquire the data, not create or restore the backup file.
Procedure
1.Choose File > Make Backup.
▪In the Backup Experiment window, enter a name for your experiment backup file, and browse to the location in which you want to store your experiment backup file.
▪Choose the backup options (see below).
2.Copy or send the *.evz file to the final destination.
3.Restore the backup on the second computer (see below).
Backup options
Select whether you want to:
▪Include Media Files: These are the video files stored in the Media Files folder of that experiment. important Video files used in that experiment but stored in other locations are not copied to the backup file.
▪Include Export Files: These are the result files and image files stored in the Export Files folder of that experiment.
▪Include External Data Files: These are the physiological data files stored in the External folder of that experiment.
▪Make backup read-only. When you select this option you get a warning in case you (accidentally) delete the backup file.
Notes
▪The backup file has the extension *.evz. The file name must not contain any of the following characters: / : * ? \ “ < > | . ; .
▪important Your backup files can get very big if you include your media files!
▪If you have recently carried out batch statistics calculations, the backup file may be unnecessarily large. To reduce file size, for each Track Smoothing profile in your experiment click two times a Track smoothing option (see details below). Next, make a backup.
▪Make sure that your media files, export files and external data files are within the experiment folder, otherwise they will not be included in the backup.
▪You should store the backup file on a secure medium (preferably a network drive), in a separate location.
▪When you carry out batch statistics calculations, EthoVision XT stores the results in a number of files, one for each combination of Track Smoothing profiles, Data profiles, Analysis profiles, dependent variable, track, etc. These files are stored in the Intermediate sub-folder in the experiment folder. A large number of result files can make the backup file exceedingly large especially when you deal with a large number of tracks and/or profiles. To remove the result files, open a Track Smoothing profile that you used for analysis and click an option two times, whether that option was selected or not:
Do this for all Track smoothing profiles that you used for analysis. Next, make a backup of your experiment.
To restore the batch calculation results, repeat the batch calculation procedure.
To restore an experiment from the backup file
1.Choose File > Restore Backup, or in the EthoVision Startup window, under Restore experiment, click Restore backup.
2.Browse to the location where your backup file is stored, select it and click Open.
3.Browse to the location where you want to save the experiment and click OK.
The experiment folder and all associated files of the experiment are restored.
Do one of the following:
▪Choose File > Restore Backup. In the window that opens, click the backup file you want to delete and press the Delete. Click Yes to confirm.
▪In Windows File Explorer, browse to the experiment backup file (*.evz) and delete it.
