Normalize Plates (B-Score)

Each plate will be normalized by applying the B score. The B score algorithm uses an iterative 'median polish' procedure.

In brief, the algorithm uses robust plate, row and column estimates to eliminate plate, row and column position biases that result e.g. from egde effects.

Note: The node expects the presence of integer columns named 'plateRow' and 'plateColumn' containing the well position.

Options

Group wells by
Select the column to define the plates (e.g. "barcode").
Normalize
Select the columns with data to be normalized.
Replace existing values
If checked the raw values will be replaced by the normalized values. Otherwise columns with the normalized values will be appended (.bscore).
