copy_ome_zarr_hcs_plate
Task that copies the structure of an OME-NGFF zarr array to a new one.
_generate_plate_well_metadata(zarr_urls)
¶
Generate metadata for OME-Zarr HCS plates & wells.
Based on the list of zarr_urls, generate metadata for all plates and all their wells.
PARAMETER | DESCRIPTION |
---|---|
zarr_urls |
List of paths or urls to the individual OME-Zarr image to be processed. |
RETURNS | DESCRIPTION |
---|---|
plate_metadata_dicts
|
Dictionary of plate plate metadata. The structure is: {"old_plate_name": NgffPlateMeta (as dict)}. |
new_well_image_attrs
|
Dictionary of image lists for the new wells. The structure is: {"old_plate_name": {"old_well_name": [ImageInWell(as dict)]}} |
well_image_attrs
|
Dictionary of Image attributes of the existing wells. |

copy_ome_zarr_hcs_plate(*, zarr_urls, zarr_dir, method=DaskProjectionMethod.MIP, overwrite=False)
¶
Duplicate the OME-Zarr HCS structure for a set of zarr_urls.
This task only processes the zarr images in the zarr_urls, not all the images in the plate. It copies all the plate & well structure, but none of the image metadata or the actual image data:
- For each plate, create a new OME-Zarr HCS plate with the attributes for all the images in zarr_urls
- For each well (in each plate), create a new zarr subgroup with the same attributes as the original one.
Note: this task makes use of methods from the Attributes
class, see
https://zarr.readthedocs.io/en/stable/api/attrs.html.
PARAMETER | DESCRIPTION |
---|---|
zarr_urls |
List of paths or urls to the individual OME-Zarr image to be processed. (standard argument for Fractal tasks, managed by Fractal server). |
zarr_dir |
path of the directory where the new OME-Zarrs will be created. (standard argument for Fractal tasks, managed by Fractal server).
TYPE:
|
method |
Choose which method to use for intensity projection along the Z axis. mip is the default and performs a maximum intensity projection. minip performs a minimum intensity projection, meanip a mean intensity projection and sumip a sum intensity projection.

RETURNS | DESCRIPTION |
---|---|
dict[str, Any]
|
A parallelization list to be used in a compute task to fill the wells |
dict[str, Any]
|
with OME-Zarr images. |
