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

Dialog 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.
