Select relevant columns of data Scenarios
Scenario Type Detail
Relevant columns of data Basic Path BP network has some inputs and outputs. Inputs are values that are inserting into the network and outputs are desired outputs of the network. Selecting which columns are used is critical for network training. Some columns (as primary key) should not be used for classification.

The user always have to select some columns before commiting (with "OK button") - a control is beeing made.
Data Structures for input/output columns Basic Path There are two Arraylists with numbers of selected columns.
- Arraylist Form1.InputColumns contains numbers of input columns
- Arraylist Form1.OutputColumns contains numbers of output columns

When a new version of data is loaded, both structures are deleted and again created. Because the old arraylists were prepared for the old one version of data.
