normalize_spatialdata(sdata, table_name[, method, inplace])	Normalize intensities per pixel in a SpatialData object.

Module Contents

goatpy.preprocessing.normalize_matrix(X, method='TIC', eps=1e-12)

Normalize a (n_pixels × n_mz) matrix.

goatpy.preprocessing.normalize_spatialdata(sdata: spatialdata.SpatialData, table_name: str, method: str = 'TIC', inplace: bool = False)

Normalize intensities per pixel in a SpatialData object.

Parameters:

• sdata (SpatialData)

• table_name (str) – Name of the table containing intensities (pixels × mz)

• method ('TIC' | 'RMS')

• inplace (bool) – If False, returns a new SpatialData object
