Spliting substes of time of a Ns3 file

[G00Z-G00Z]

Hello! I have a problem splitting the ns3 files.

So in my application, we are running some trials at specific time interfvals.
However, we do not turn off the sensor when we are making the trials

For example:

1. We turn on the sensor

t	Action	Duration
t=0	Take trial one	10secs
t=10	wait	40secs
t=50	Take trial two	10secs
t=60	Take trial three	10secs
t=70	wait	5secs
t=75	Take trial four	10secs

8. Turn off the sensor

This produces a very large .nsx & .nev files due to the wait times.
Using the python utilities, I already have the exact intervals of trials.
However, we'd like to save subsets of nsxfiles with the specific time lenght of the trials:

E.g:

• trial-001.nsx (t=0, 30secs)
• trial-002.nsx (t=50, 10secs)
• trial-003.nsx (t=60, 10secs)
• trial-004.nsx (t=75, 10secs)

The Nsx api allows to save subsets of time, but not specific intervals of time.

Is there a way to save a specific interval of time?
Also, another alternative using the subsets would be to create smaller substes
and then combine them to generate the interval I need...

Thanks for your time
