If you say so. I do not know about fMRI. But one sample each 2.8 seconds sounds too slow to me. any way, you can change that later if you find otherwise. change fs below, which is the sample rate of the data.

btw, this looks like a very low sample rate. You can adjust the code below if you think it is different. 0.357 samples per second is very low but you can check it on your end. If you meant it was 2800 samples per second, then change fs below to 2800.

| Feb 3, 2014 at 11:07 | comment | added | holistic | @Nasser: It's data from an fMRI scan. So a scan was done every 2800 ms. Sorry, I'm just trying to get more into this stuff :/ | |
