• To export the averages, totals, etc. per trial or per group of trials, choose Analysis > Export > Statistics.
• To export the raw x,y coordinates and the surface area of the subject, or the per-sample values of the dependent variables, choose Analysis > Export > Raw Data.

For details, see File Management > Export data in the EthoVision XT Help.
