If I were to follow the first route, my understanding is that I do not have
to modify the default reconstruction chain. I just have to supply the
SeqVector to the SeqObjLoop and in the reconstruction parameter
set supply this to the epiadc.set_reco_vector(average, vector).
Now, do I have to do the same for the repetition loop?
Current odinepi sequence simply repeats the sequence body N times
without supplying any information to the recon. However, it appears that
"repetition" index exists. I have tried to add it to the recon
parameters and it failed.
I mean the sequence compiles, but the sequence diagram is not generated causing
a segmentation fault.
Somehow, I have managed to add the average index to the recon code...

Are the counters added differently? I do not think so. Maybe the
repetition vector
is not needed? just repeat the sequence and that is all?

Thanks for your help
