Hi,
I hope I’m not missing something obvious here, but I can’t seem to see a logical relation between some of the times indicated in my log files and my .csv output file.
For example, (using builder view) I have my sound file and my recording mic start at the same time in my design. In the .csv output file, the start time for the sound file does not appear to line up consistently with anything in the log file.
Basically, I need to identify from this information what is the most reliable times to use to splice the EEG data file recorded simultaneously to the correct start and stop times for my sound files. I was assuming (perhaps incorrectly) that the log file was more accurate, but I get a more precise time (as in, more decimal places) in the .csv file, which is useful.
