===== Reading Output =====
When an EPrime experiment runs, it saves a ''.edat3'' and mirrored ''.txt'' files to record outcomes (RT, button pushes) and event timing (onsets).
''[[https://support.pstnet.com/hc/en-us/articles/115012298367-E-DATAAID-Exporting-and-Importing-Data-22832|E-DataAid]]'' can convert the edat3 file to csv.

External tools can parse the ''.txt'' file. Those include:
  * R package [[https://github.com/tjmahr/rprime|rprime]]
  * Python tool [[https://pypi.org/project/eprime_data/|eprime_data]]
  * perl script [[https://github.com/lncd/lncdtools/blob/master/eptxt|eptxt]]
