This package includes very basic support for loading GIFTI (.gii, .gii.gz) files in Julia. Currently only the surface mesh can be extracted, represented as a Mesh from GeometryBasics.jl.
using GIFTI
using GLMakie
using GeometryBasics
# Load Mesh
example_mesh = GIFTI.load(GIFTI.assetpath("infl_left.gii.gz"))
# Visualize via Makie
f = Figure(backgroundcolor=RGBf(1, 1, 1),resolution=(1200, 800))
ax = Axis3(f[1, 1], title="fsaverage5: left hemisphere inflated pial surface mesh", aspect=:data)
mesh!(ax, example_mesh, color=rand(length(coordinates(example_mesh))))
