mvpa2.misc.plot.flat_surf.FlatSurfacePlotter

class mvpa2.misc.plot.flat_surf.FlatSurfacePlotter(surface, curvature=None, min_nsteps=500, range_='2_98%', threshold=None, color_map=None, max_deformation=0.5)

Plots data on a flat surface

Methods

__call__(data)	Parameters:
set_underlay(u)	Sets the underlay

Parameters:

surface: surf.Surface

a flat surface

curvature: str or np.ndarray

(Filename of) data representing curvature at each node.

min_steps: int

Minimal side of output plots in pixel

range_: str or float or tuple

If a tuple (a,b), then this tuple is returned. If a float a, then (-a,a) is returned. “R(a)”, where R(a) denotes the string representation of float a, is equivalent to range_=a. “R(a)_R(b)” is equivalent to range_=(a,b). “R(a)_R(b)%” indicates that the a-th and b-th percentile of xs is taken to define the range. “R(a)%” is equivalent to “R(a)_R(100-a)%”

threshold: str or float or tuple

Indicates which values will be shown. Syntax as in range_

color_map: str

colormap to use

max_deformation: float

maximum deformation to make a non-flat surface flat. The normals of each face must have a dot product with the average face normal that is not less than (1-max_deformation); otherwise an exception is raised. The rationale for this option is that certain surfaces may be almost flat, and projecting the vertices on a truly flat surface should be fine. On the other hand, surfaces that are definitly not flat (such as full cortical surface models) should cause an error to be raised when it is attempted to flatten them

Methods

__call__(data)	Parameters:
set_underlay(u)	Sets the underlay

set_underlay(u)

Sets the underlay
