I'm gonna check this out. I may have fixed this according to the tests we were looking at, but introduced a bug elsewhere.A QA test involving the moving average blocks and stream tags might help clear things up.On Thu, Dec 31, 2015 at 10:38 AM, Tom Rondeau <address@hidden> wrote:_______________________________________________On Wed, Dec 30, 2015 at 3:32 PM, <address@hidden> wrote:
It’s a tag generator that goes through several other blocks before getting to the tag receiver.

Basically I’m computing the ration of a fast average to a slow average and sending that to a threshold detector sink (tag receiver) to watch for the signal to go above threshold. It then sends a message with the time stamp of that event to another block for other processing. I wrote the tag generator and tag receiver.
Mark.I'd recommend plugging the tag generator directly into the tag receiver just to make sure both of those are handling the tags properly. If they are, then we can dive into the rest of the chain to see where things might be having problems. My guess is that it'll be related to the different delays of the moving average filters.This also might be related to a bug that we recently patched:Tom
