Feature Table

Writes selected features of the incoming network to a data table.

A one value column table represents all values in own column. It also contains a feature type column (e.g. string, float, ...) and a feature name column. Example of a one value column table:

Feature target Graph id Edge id Node id Feature name Feature type Feature value
graph ID ? ? Description string Bla bla bla
node ID ? Node1 label string Label1
edge ID Edge1 ? weight float 1.0
end ID Edge1 Node2 is_target boolean true

A table with separate value columns contains for each value a separate column. The example table from above would look like the following:

Feature target Graph id Edge id Node id Description label weight is_target
graph ID ? ? Bla bla bla ? ? ?
node ID ? Node1 ? Label1 ? ?
edge ID Edge1 ? ? ? 1.0 ?
end ID Edge1 Node2 ? ? ? is_target

Options

Features
The selected features are written to the output table.
Table type
The separate value column option contains for each value a separate column whereas the one value column type contains one creates a table that contains the feature name and value in one column. In a wide table each feature has its own column.
Node id
The optional column that contains the id of the nodes to extract the feature values for. If node and edge id column are given they are treated as an end object.
Edge id
The optional column that contains the id of the edges to extract the feature values for. If node and edge id column are given they are treated as an end object.
