Chaining successive Time-based epoching
Posted: Mon Jun 13, 2016 10:48 am
Hi,
I was trying to create a scenario involving multiple uses of "Time Based Epoching" in a raw.
More precisely, I understood that the output of "Time Based Epoching" is slices of signal with possible overlap: this is not exactly a new continuous signal then.
However, if I use then a Box like Signal Average, I understood that the output was a regular signal again.
For instance, let's say I do "Time Based Epoching" with length 2s every 1s, followed by Signal Average, I should have a regular signal with sample value every second, on which I should be able to apply Time Based Epoching again.
But when I try "Mediane" on the new output signal, and I try to display it, I get nothing, with an error involving 0 sampling rate.
Note that if I used "Epoch Average", it works but there's apparently no Epoch Median, and in any case I would like to be able to do multiple successive epoching.
My question is: is it possible to convert the output of the "Time Based Epoching" + some processing that turns slices of signal into a unique scalar value (like signal average) back to a regular signal, on which it is possible to apply any Box that accepts regular signal as Input, like "Time Base Epoching" again for instance. Or is there a work around ?
Thanks in advance!
