I have to reproduce the problem to fix it. Why don't you go and modify midas/examples/experiment/frontend.cxx in such a way that
it creates exactly the banks you have, just with random data. If you see the same problem, send me your frontend file so that I
can reproduce it. |

Today I addressed a topic which bugged me since long time. The ODB contains
settings under /Equipment/<name>/Common which are a "mirror" of the equipment[]
setting in a frontend (using the mfe.cxx framework). If the "Common" entry in

The history code is right now programmes in such a way that when you request

gets loaded. When we implemented that, this worked fine for data ranges of

There is no "mechanism" foreseen to be executed after each subrun. But you could
run a shell script after each run which loops over all subruns and converts them
one after the other.

First, the writing of banks is completely independent of the history system. Banks go to the log file only,
while the history is only linked to the "Variables" section in the ODB.
