I tried all your suggestions. Im sure they all would work but the point is that it takes hours to run ... I did not wait for the result because my SAS EG started to crash and it took me to long.
In the usable data I showed you above I indeed asked for the first 3 and last 3 seconds, but in the original data 1 measurement is much much longer (approx. 40 seconds and it has around 1500 records). And every day has maybe hundreds of measurements and the I have data of more then 1,5 year.. So you can already count how much records I have. Should be millions+. Got such a headache from this continually crashing...
