How to record the duration of the entire experiment and store it in the data CSV?

Hi,

I want to record the duration of the entire experiment and store it in the data CSV along with all of the other data.

I'm using jsPsych.data.checks = jsPsych.data.getInteractionData().last(1) but it doesn't appear in my final CSV file.

The code to save data in CSV is:
`function save_data_csv() {
jQuery.ajax({
type: 'post',
cache: false,
url: save_url,
data: {
data_dir: data_dir,
file_name: file_name + '.csv', // the file type should be added
exp_data: jsPsych.data.get().csv()
}
});
}

jsPsych.init({
timeline: timeline,
display_element: 'display_stage',
preload_images: preload_list,
on_finish: function () {
save_data_csv();
}
});`

Thanks for the help!

Hi @zz112duke,

This is already saved in the data by default. A column called total_time_elapsed is saved with each trial, which records the time since the start of the experiment to the end of that trial. The final trial will be the duration of the entire experiment.

It turned out that I had too many columns so I missed it. Thank you so much!
