Condition table¶

A condition table represents experimental conditions or metadata associated with images or experiments. It is a flexible table type, so it can hold any kind of metadata about them.

Example condition table:

Specifications¶

V1¶

A condition table must include the following metadata fields in the group attributes:

{
    // Condition table metadata
    "type": "condition_table",
    "table_version": "1",
    // Backend metadata
    "backend": "csv", // the backend used to store the table, e.g. "anndata", "parquet", etc..
    "index_key": "condition_id", // Optional. The column used as the row index.
    "index_type": "str" // Optional. Either "int" or "str"
}

As with generic tables, a condition table has no default index: index_key and index_type appear only when you set one.

In ngio this table type is the ConditionTable class.
