[ome-users] dm4 imports with um scale instead of nm

[Will Moore]

Hi Ralph,

Unfortunately the OME schema does not support variable units for each attribute of the model. They are "hard coded" and for
pixel size it is microns. The ticket for adding support for different units is https://trac.openmicroscopy.org.uk/ome/ticket/3741

Cheers,

   Will.
