Selection of a signal area to detect fixed point

Hello,

I would like to ask how can i select a specific area of a 20000x1 timesieries of an ECG signal? I want to take an area from the ECG's histogram in order to write a code for fixed/end point detection, but even though i tried with brush tool, i still can't. Is there any way? (i am new to matlab)

Thank you!!

You could use the "getsamples" function programmatically which returns subset of the timeseries in a specified time region. This is similar to brush where you get the rectangular area selecting the timeseries values.
