Images and Plates

To export Images or Plates via the OMERO API:

# Image will be saved in current directory as 1.zarr
$ omero zarr export Image:1

# Plate will be saved in current directory as 2.zarr
$ omero zarr export Plate:2

# Specify an output directory
$ omero zarr --output /home/user/zarr_files export Image:1

# Cache each plane as a numpy file.npy. If connection is lost, and you need
# to export again, we can use these instead of downloading again
# omero zarr --cache_numpy export Image:1

To export images via bioformats2raw we use the `--bf` flag:

export MANAGED_REPO=/var/omero/data/ManagedRepository
export BF2RAW=/opt/tools/bioformats2raw-0.2.0-SNAPSHOT

$ omero zarr --output /home/user/zarr_files export 1 --bf
Image exported to /home/user/zarr_files/2chZT.lsm

Masks and Polygons

To export Masks or Polygons for an Image or Plate, use the masks or polygons command:

# Saved under 1.zarr/labels/0 - 1.zarr/ must already exist
$ omero zarr masks Image:1

# Labels saved under each image. e.g 2.zarr/A/1/0/labels/0
# Plate should already be exported
$ omero zarr masks Plate:2

# Saved under zarr_files/1.zarr/labels/0
$ omero zarr --output /home/user/zarr_files masks Image:1

# Specify the label-name. (default is '0')
# e.g. Export to 1.zarr/labels/A
$ omero zarr masks Image:1 --label-name=A

# Allow overlapping masks or polygons (overlap will be maximum value of the dtype)
$ omero zarr polygons Image:1 --overlaps=dtype_max

The default behaviour is to export all masks or polygons on the Image to a single 5D “labeled” zarr array, with a different value for each Shape. An exception will be thrown if any of the masks overlap, unless the –overlaps option is used as above.

An alternative to handle overlapping masks is to split masks into non-overlapping zarr groups using a “label-map” which is a csv file that specifies the name of the zarr group for each ROI on the Image. Columns are ID, NAME, ROI_ID.

For example, to create a group from the textValue of each Shape, you can use this command:

omero hql --style=plain "select distinct s.textValue, s.roi.id from Shape s where s.roi.image.id = 5514375" --limit=-1 | tee 5514375.rois

This creates a file 5514375.rois like this:

0,Cell,1369132
1,Cell,1369134
2,Cell,1369136
...
40,Chromosomes,1369131
41,Chromosomes,1369133
42,Chromosomes,1369135
...

This will create zarr groups of Cell and Chromosomes under 5514375.zarr/labels/:

$ omero zarr masks Image:5514375 --label-map=5514375.rois
