About reproducing the reaction time from log file

[WeiHsiang_Lin]

Description of the problem:

Hi, I am running an experiment and saved data into the database.
I found one of the subject’s responses and reaction time is not on the csv file.
However, the log file has them.
Can I manually reproduce the response time by minus the timestamp of the response and the cue time stamp?
Like the following figure, minus the timestamp of KeyDown to the timestamp of text:autoDraw

Thanks!

(2) Further, does the response time , in log as well as in the csv file, record the time of the keypress onset or the time of the key release? (3) …
