hippunfold_plot 0.1.1

Plotting functions for hippocampal surface maps from HippUnfold

🧠 hippunfold_surf

This package provides plotting functions for hippocampal surface maps from HippUnfold (https://github.com/khanlab/hippunfold), wrapping the Nilearn (https://nilearn.github.io) plotting functions (matplotlib engine) to achieve this.

Note: these plotting functions are distinct from those in HippoMaps (https://github.com/MICA-MNI/hippomaps), which use VTK wrappers and have a number of limitations therein.

This package is new and still under active development so suggestions and pull-requests are welcome!

📦 Installation

To install the package, simply run:

pip install hippunfold_plot

🚀 Usage

Here are some examples of how to use the plot_hipp_surf function to visualize hippocampal surface maps.

Example 1: Plot Both Hemispheres

from hippunfold_plot.plotting import plot_hipp_surf
from hippunfold_plot.utils import get_resource_path

#get subfields for demonstrating plotting
label_gii = get_resource_path('tpl-avg_label-hippdentate_density-{density}_subfields.label.gii')
density = '1mm'

# Plot dorsal view
fig = plot_hipp_surf(label_gii.format(density=density), hemi=None, density=density, view='dorsal')

# Plot ventral view
fig = plot_hipp_surf(label_gii.format(density=density), hemi=None, density=density, view='ventral')

Example 2: Plot Left and Right Hemispheres Separately

from hippunfold_plot.plotting import plot_hipp_surf
from hippunfold_plot.utils import get_resource_path

#get subfields for demonstrating plotting
label_gii = get_resource_path('tpl-avg_label-hippdentate_density-{density}_subfields.label.gii')
density = '1mm'

# Plot left hemisphere
fig = plot_hipp_surf(label_gii.format(density=density), hemi='left', density=density, view='dorsal')

# Plot right hemisphere
fig = plot_hipp_surf(label_gii.format(density=density), hemi='right', density=density, view='dorsal')

Example 3: Plot unfolded and canonical space separately

from hippunfold_plot.plotting import plot_hipp_surf
from hippunfold_plot.utils import get_resource_path

#get subfields for demonstrating plotting
label_gii = get_resource_path('tpl-avg_label-hippdentate_density-{density}_subfields.label.gii')
density = '1mm'

# Plot left hemisphere in unfolded space
fig = plot_hipp_surf(label_gii.format(density=density), space='unfold', density=density, view='dorsal')

# Plot left hemisphere in canonical space
fig = plot_hipp_surf(label_gii.format(density=density), space='canonical', density=density, view='dorsal')

    can also be applied here, overriding the defaults set below.    """
