I think that If we have time we can try:
why we need 4 different collections?
Now we run all four seeds in parallel and we can drop this
distinction and run on only one collection:
what do you think?

You need to get separate tcl files for each skim.
Which brings us to an important question. Somebody (perhaps Ric and
Daniele) set up semi-exclusive collections by mode:
declarePath BToDstarSemiExclPath Breco/BToDstarSemiExcl Merged/Stream06 BrecoStream
declarePath BToDcSemiExclPath Breco/BToDcSemiExcl Merged/Stream06 BrecoStream
declarePath BToDstar0SemiExclPath Breco/BToDstar0SemiExcl Merged/Stream06 BrecoStream
declarePath BToD0SemiExclPath Breco/BToD0SemiExcl Merged/Stream06 BrecoStream
This means that if you want to run over all these events, you need to
run 4 jobs (or configure your job to read 4 collections). Issues of
event duplication etc. will clearly come up. I am not sure why it was
set up this way -- historic, perhaps, or maybe despite my numerous
talks and posts on the subject, the difference between skims and
streams was not clearly understood. Basically, streams were an
artificial construction, for data distribution: built originally for
Kanga, and migrated into Objy temporarily in release 10. You should
have never relied on all these events being in one stream. If you
wanted one giant collection for all semi0-exclusive modes, you should
have defined one collection in FilterTools.
So my question is -- do you want 4 collections, or 1 collection ? If
you want a single collection, there is still time (until early Sunday)
to change this setup for release 12 (Padova) reprocessing. Otherwise,
you will be getting 4 collections for each run next year.
Do I need to forward this question to vub-recoil list ?
Cheers,
Yury
