How to add the timestamps according to what

you can add timestamp with your office software, if csv use maybe excel or google sheet. Or maybe you can use python pandas to add the timestamps columns.

example you have 100 data, with acquisition duration = 10 second.
so your timestamps interval are 10000 ms/100 = 100.
according to the interval value, your data with timestamp column would like this:

Thank you sooo much . So can i add the repetitions movements into one file with the whole subjects as I mentioned i have 10 classes and each classes has repetitions 6 times for each of one subject where the total subjects are 8 so how can I handle that

im still facing the same issue eventhough after i did the timestamp

You are using name “Timestamp” on your column, the correct name is “timestamp”. use all lower character

thanks manged to solve it
