That probably works.

Not really, the ScreenAcquisition is a container for all well samples
and thus all wells. What I'm looking for is an object that is the
collection of all well samples acquired in *one* well during one
ScreenAcquistion. One would have n of these containers if n is the
number of wells measured in the ScreenAcquisition.
If you think this is useful, it would be nice to consider adding this
kind of container.

Otherwise, for the well result annotation I would like to store, I
think it's possible to link the result annotation to a well and to a
ScreenAcquisition, this would allow to select the results per well and
acquisition.

Thanks again! Bernhard
