Yeah - these things should be caught.

We will add somethign to the readme - (@alexomics) - unfortunately this particular scenario hasn't happened on any of our testing machines - it's just been reported to us.

This is a frustrating issue which we think is caused by the MinKNOW RPC.

It appears that the RPC reports that it is ready but actually isn't - and this may be millisecond timing.

My advice at present would be to wait until the run is actually started before starting ru_generator.

I'll tag @alexomics for any further comment.

Thanks! Good to know it's probably not a configuration error on our side or something.

If you check MinKNOW during a normal start, it actually gives a "Finishing up" status somewhere during the initialization (I added a screenshot). Could be related to that?

In the meantime, maybe I missed it but it could be helpful to add that this situation can occur to the instructions?
