omero-metadata 0.10.0

populate

This command creates an OMERO.table (bulk annotation) from a CSV file and links the table as a File Annotation to a parent container such as Screen, Plate, Project Dataset or Image. It also attempts to convert Image, Well or ROI names from the CSV into object IDs in the OMERO.table.

The CSV file must be provided as local file with --file path/to/file.csv.

If you wish to ensure that number columns are created for numerical data, this will allow you to make numerical queries on the table. Column Types are:

• d: DoubleColumn, for floating point numbers

• l: LongColumn, for integer numbers

• s: StringColumn, for text

• b: BoolColumn, for true/false

• plate, well, image, dataset, roi to specify objects

These can be specified in the first row of a CSV with a # header tag (see examples below). The # header row is optional. Default column type is String.

NB: Column names should not contain spaces if you want to be able to query by these columns.

Project / Dataset

To add a table to a Project, the CSV file needs to specify Dataset Name and Image Name or Image ID:

$ omero metadata populate Project:1 --file path/to/project.csv

project.csv:

# header s,s,d,l,s
Image Name,Dataset Name,ROI_Area,Channel_Index,Channel_Name
img-01.png,dataset01,0.0469,1,DAPI
img-02.png,dataset01,0.142,2,GFP
img-03.png,dataset01,0.093,3,TRITC
img-04.png,dataset01,0.429,4,Cy5

This will create an OMERO.table linked to the Project like this with a new Image column with IDs:

If the target is a Dataset instead of a Project, the Dataset Name column is not needed.

Screen / Plate

To add a table to a Screen, the CSV file needs to specify Plate name and Well. If a # header is specified, column types must be well and plate.

screen.csv:

# header well,plate,s,d,l,d
Well,Plate,Drug,Concentration,Cell_Count,Percent_Mitotic
A1,plate01,DMSO,10.1,10,25.4
A2,plate01,DMSO,0.1,1000,2.54
A3,plate01,DMSO,5.5,550,4
B1,plate01,DrugX,12.3,50,44.43

This will create an OMERO.table linked to the Screen, with the Well Name and Plate Name columns added and the Well and Plate columns used for IDs:

If the target is a Plate instead of a Screen, the Plate column is not needed.

ROIs

If the target is an Image or a Dataset, a CSV with ROI-level or Shape-level data can be used to create an OMERO.table (bulk annotation) as a File Annotation linked to the target object. If there is an roi column (header type roi) containing ROI IDs, an Roi Name column will be appended automatically (see example below). If a column of Shape IDs named shape of type l is included, the Shape IDs will be validated (and set to -1 if invalid). Also if an image column of Image IDs is included, an Image Name column will be added. NB: Columns of type shape aren’t yet supported on the OMERO.server.

Alternatively, if the target is an Image, the ROI input column can be Roi Name (with type s), and an roi type column will be appended containing ROI IDs. In this case, it is required that ROIs on the Image in OMERO have the Name attribute set.

image.csv:

# header roi,l,l,d,l
Roi,shape,object,probability,area
501,1066,1,0.8,250
502,1067,2,0.9,500
503,1068,3,0.2,25
503,1069,4,0.8,400
503,1070,5,0.5,200

This will create an OMERO.table linked to the Image like this:

Note that the ROI-level data from an OMERO.table is not visible in the OMERO.web UI right-hand panel under the Tables tab, but the table can be visualized by clicking the “eye” on the bulk annotation attachment on the Image.
