I am trying to compute cross-correlation matrix around P arrival times of some events.
When I trim the data around P arrival, some traces have lenght 20 and some 21. How should I deal with this problem? Changing nearest_sample in trim helps sometimes, but not always. The len of traces changes from example to example so I cant force for all examples the lenght with:
if len(data) > 20.0:
data = data[:-1]
data = data
