Tools

Tools fields in Ango Annotation Format exports.

The tools object is part of the task object in the Ango Annotation Format. It contains all annotation data pertaining to labels created with tools, e.g. not classifications, relations, or brushes.

Annotations created with the following annotation tools will appear in the tools object:

Annotations created with the Brush and Voxel Brush tools are not saved here. They are instead saved, respectively, in the brushDataUrl and the medicalBrushDataUrl objects within the task object. See the page on the Task object for more.

That said, if the voxel brush in your project has nested classifications, the nested classification contents will appear here.

The page property, in the export, is 0-indexed, while in the Ango Hub user interface it is 1-indexed.

What this means in practice is that pages start at 0 in the export, but 1 in the UI.

So for example, if, in the UI, you create a bounding box at page "12", it will appear under page "11" in the export.

General Structure

"tools" : [{
    bounding-box OR rotated-bounding-box OR polygon OR polyline OR segmentation OR ner OR point OR pdf OR spline// object, tool coordinate info
    objectId // string, ID of the object
    schemaId, // string, ID of the labeling tool in the project
    classifications, // list, nested classifications
    title // string, title of the tool
    page // int, page where the object is located (only multi-page, non-video assets)
    medical-brush, // bool, true if the current tool is a medical brush
    },
    { ... }
]

Common Properties

Property	Type	Description
objectId	String	Object ID of the tools. Unique in the asset. "objectId": "6b8a4338d299c63b5ee7825"
classifications	List	List of nested classifications (if any). May contain further nested classifications in its own classifications property. Each object in the list is of the classification format. See its docs page for more information. "classifications": [ { "objectId": "78d263ed59db8dd1dcb4666", "schemaId": "4460fa700ef030c4e575604", "tool": "radio", "title": "Nested Radio", "answer": "1", "metadata": { "createdAt": "2023-09-05T10:28:18.667Z", "createdBy": "[e-mail]", }, "classifications": [] } ]
schemaId	String	ID of the class to which the object belongs. "schemaId": "4460fa700ef030c4e575604"
title	String	Name of the class to which the object belongs. "title": "Vehicle"
metadata	Dict	Only appears if the Annotation Metadata toggle has been turned on before export. createdAt: int, Time of creation in Unix epoch time in milliseconds. GMT. createdBy: string, email of user creating the object updatedAt: int, optional. Time of last object update in Unix millisecond epoch time. GMT. Only appears if object has been updated. updatedBy: string, optional. email of user last updating the object. Only appears if object has been updated.

Medical Reformat Metadata

In the Medical Labeling Editor, Point, Polygon, and Polyline annotations can be created on a reformatted oblique plane. When this happens, the export includes an nrrdReformat object on the annotation:

"nrrdReformat": {
    "activePlane": "Axial",
    "angle": 12.5,
    "centerVoxel": [
        123,
        139,
        60
    ]
}

activePlane is the original view used as the reformat plane, angle is the reformat angle, and centerVoxel is the voxel used as the center of the oblique view. These values describe the reformatted view used when the annotation was created or last edited. The annotation coordinates themselves are still exported as 3D voxel coordinates, with patient-space coordinates where available.

Voxel Brush annotations do not include per-annotation nrrdReformat metadata. They are exported as the final 3D segmentation volume through medicalBrushDataUrl in the task object. 3D Bounding Box annotations are exported as their normal 3D coordinates and do not include nrrdReformat.

Coordinates in the Ango Annotation Format

This is the coordinate system used when determining the position of points in the Ango export.

The origin point lies at the top left corner, and each point has a (X, Y) coordinate pair determining its position, in pixels, on the image.

Changes in Video Assets

Video assets have a slightly different format for the "tools" property:

"tools" : [{
    schemaId, // string, ID of the labeling tool in the project
    objectId, // string, ID of the object
    segments, // list, start and end frames of segments for this class
    keyFrames, // object, list of keyframes for this annotation for this class
    bounding-box OR rotated-bounding-box OR polygon OR polyline OR segmentation OR ner OR point OR pdf OR spline// object, tool coordinate info
    lock, // bool, whether this object has been locked from being edited or not
    ocr, // bool, whether this object had OCR enabled or not (bounding-box only)
    metadata, // object, metadata about the object,
    outOfViewSegments, // list, start and end frames for out-of-view portions for this class
    classifications, // list, nested classifications, following the same format as parent
    },
    { ... }
]

We recommend examining a sample export from Ango Hub to better understand how it fits together, such as the following:

Segmentation

Segmentation point coordinates will not be visible in your export unless you activate the "Segmentation Points" toggle in the Export tab under the Fields dropdown.

Metadata for segmentations will not appear even when enabling the Annotation Metadata toggle in the export settings.

Segmentations are composed of instances, zones, regions, and holes.

An instance may contain more than one zone. One zone contains exactly one region. A region can contain more than one hole.

Each of the points composing the segmentation is represented as an X/Y coordinate pair.

"segmentation": { "zones": [ { "region": [ [ 313.162, // x 414.94. // y ], [ 313.717, 411.981 ], [ 316.517, 397.045 ] ], "holes": [] }, { "region": [ [ 369.814, 331.194 ], [ 376.151, 328.957 ], [ 389.216, 324.346 ] ], "holes": [ [ [ 406.712, 372.575 ], [ 407.344, 380.782 ], [ 409.238, 388.358 ] ] ] } ] }
