Color Map manipulation

When it comes to the visualization the brain map, it is wise to attach an appropriate color map. The choice of the color map depends on the type of the data and the message to convey to the readers.

Pre-defined Color Maps

For example, the gradient color map was designed to highlight the very high and very low values, which corresponds to the information by functional gradient.

>>> from neurocat import color
>>> color.cmap.gradient()

Besides, neurocat made some commonly used color map that don’t exit in matplotlib. They were all stored in neurocat.color.cmap.

Myeline map:

>>> color.cmap.myelin()

``psych_no_none``(from connectome workbench):

>>> color.cmap.psych_no_none()

Hot map but without black

>>> color.cmap.hot_no_black()
