nimare.studyset.LabelBlock

class LabelBlock(values: object, labels: ndarray, rows: ndarray, _col_of: dict = <factory>)

Bases: object

The annotation matrix, column-major.

Decoders address it by label, so it is stored CSC: one column is a contiguous slice. Stored CSR, getcol is O(total nonzeros) and the per-feature cost collapses as the label count grows.

Methods

above(label, threshold)	Boolean mask: this label at or above threshold.
col(label)	Return the column index of label.
column(label)	One label's values as a dense float array over the view's analyses.
dense([labels])	Build a dense matrix for the requested labels.
