Create WellSample in Python throws error

Postby andersla » Wed Mar 06, 2019 1:47 pm

I have created a Screen, Plate, Well and Image OK.

Trying to create a WellSample and linking it to the Image and Well throws error (below)

Code: Select all
def createWellSample(wellID, imageID):
  conn = getOmeroConn()
  wellSample = omero.model.WellSampleI()
 
  image = conn.getObject("Image", imageID)
  wellSample.setImage(omero.model.ImageI(imageID, False))
 
  well = conn.getObject("Well", wellID)
  wellSample.setWell(omero.model.WellI(well.getId(), False))

  wellSample = conn.getUpdateService().saveAndReturnObject(wellSample)
  obj_id = wellSample.id.getValue()
  conn.close()
  return obj_id


The error is:

Re: Create WellSample in Python throws error

Postby wmoore » Thu Mar 07, 2019 9:22 am

Hi,

I think you want to do:

Code: Select all
well.addWellSample(wellSample)


instead of:

Code: Select all
wellSample.setWell(omero.model.WellI(well.getId(), False))


There is a complete working example of this at https://github.com/dsudar/OMEROscripts/ ... ate.py#L71

If that doesn't work, let us know.
Regards,

Will.

Re: Create WellSample in Python throws error

Postby andersla » Thu Mar 07, 2019 10:09 am

Thank you so much! That pointed me in the right direction!

Just out of curiosity, If I want to load the wellSamples that are part of the well object, how do I do that?
I tried searching for well object but, the wellSamples of that object are still unloaded?
How do I "..Please refresh this object in order to update this collection.." (as said in error message

e.g.
Code: Select all
IObject well = qs.findByQuery("from Well as w where w.id=:findID", params);
well.addWellSample(wellSample);


throws error:
omero.UnloadedCollectionException: Error updating collection:wellSamplesSeq
Collection is currently null. This can be seen
by testing "wellSamplesSeqLoaded". This implies
that this collection was unloaded. Please refresh this object
in order to update this collection.

omero.UnloadedCollectionException: Error updating collection:wellSamplesSeq

in order to update this collection.

All the very best,

Dear Anders,

You need to join the collections that you want to work with. In your,
Code: Select all
... from Well as w where ...
try adjusting to,
Code: Select all
... from Well as w join fetch w.wellSamples where ...

If you need to join a whole nested tree of collections then, just as your well is "w", you could name the well samples "ws" or whatever and further join fetch from that.

Cheers,
Mark
