trend analysis with Epoch Average ?

[barten6]

Hi,
I'm trying to determine Signal Trends- I thought it might be a good idea to compare the Output and the Input of a "Epoch Average" box using 2 Inputs of a "simple DSP"-box according to the scheme shown at the end of the box' docu. The DSP does not Show any Output when connected to an "Epoch Average" box, neither when its Inputs are set to "Signal" nor when set to "stream Matrix".
Is there a Workaround for this?
Or do you recommend a better method for trend Analysis (except differentiating the Signal) ?

And here is another worry: Is there any way to make permanent Settings for Display boxes entered during execution time?

hope that someone has some ingenious advices... thanks in advance!

Hi Peter,

you should get a warning that the times of the blocks are different. The warning mentions a configuration setting that could be used to ignore it. You can also put the epoch average to an immediate mode which should help with this problem.

Currently it's not possible to save the display box settings, but this is on our todo list. We cannot promise it for the next version, however.

Happy hacking,
Jussi

Hi Jussi,

thank you so much for yr answer- farpaitement, as Obelix used to say. It's Magic! I would never have the idea to set the average-box to "immediate".
for your curiosity, I'm adding the Scenario where I used your advice.

By the way, what is the Situation concerning the Support for Cognionics HW? will there be a WORKING Driver for These devices soon?
best regards

Peter

There is a Cognionics driver in our git version and it should be in the next release (planned Jun. 2014). The driver is a contribution, meaning that inquiries wrt it should be directed to the contributing author. We do not have the device at Inria to test, so we can only test that the code compiles.


Cheers,
Jussi

coming back to yr hint (quoted above):
would be very helpful, but there isn't such a file on my PC- only files that say "do not Change", and that include not the file which is shown in the warning.
where can I find and Change the Parameter "plugin....signalproc..simpleDSP....checkChunkDates" ?
