Brain.add_ndvar_p_map(p_map, param_map=None, p0=0.05, p1=0.01, p0alpha=0.5, *args, **kwargs)

Add a map of p-values as data-layer

  • p_map (NDVar | NDTest) – Map of p values, or test result.

  • param_map (NDVar) – Statistical parameter covering the same data points as p_map. Only the sign is used, for incorporating the directionality of the effect into the plot.

  • p0 (scalar) – Highest p-value that is visible.

  • p1 (scalar) – P-value where the colormap changes from ramping alpha to ramping color.

  • p0alpha (1 >= float >= 0) – Alpha at p0. Set to 0 for a smooth transition, or a larger value to clearly delineate significant regions (default 0.5).

  • ... – Other parameters for add_ndvar().
