[ome-users] .mrc file import into omero

Hi Dan,
I just tried opening a sample .mrc file with the BioFormats
importer in imageJ.
Although there is a small amount of "original metadata" displayed
(see below), there is no metadata in the ome-xml, other than the XYZ
pixel dimensions.
I have no idea how much other metadata is associated with this .mrc
file or with a "typical" .mrc file or whether BioFormats is missing
something here?
However, the reason that the ome-xml is so poorly populated with
metadata is that EM metadata does not map onto our data model.
This fact will also cause problems when you try to import .mrc files
into OMERO and look for somewhere to put the metadata.
Your options will be to either create some structured annotations for
the various pieces of metadata, or to attach a text file with the
metadata to images.
These approaches may work on a small scale, but would not scale well
to large numbers of images.
A more complete solution would involve altering the database to model
the EM metadata.
As has been mentioned, we are planning to support EM images in OMERO
in a project spanning the next 3 years, in a collaboration with the
EM DB at EBI.
This includes building a complete data model for EM data (as we have
done for light microscopy) and implementing this in BioFormats, the
OMERO server and clients.
As the OMERO team has little experience of EM to date, any help that
you can provide in this area would be most welcome!
Many thanks,
Will.
