surface: surf.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 :
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
