Cannot tell what the problem might be. I can look at it if you can provide some more code
Here's is an example that works fine from tutorial 1, just added color_range
from brainspace.datasets import load_group_fc, load_parcellation, load_conte69
from brainspace.gradient import GradientMaps
from brainspace.utils.parcellation import map_to_labels
from brainspace.plotting import plot_hemispheres
conn_matrix = load_group_fc('schaefer', scale=400)
labeling = load_parcellation('schaefer', scale=400, join=True)
surf_lh, surf_rh = load_conte69()
gm = GradientMaps(n_components=10, random_state=0)
gm.fit(conn_matrix)
mask = labeling != 0
grad = [None] * 2
for i in range(2):
grad[i] = map_to_labels(gm.gradients_[:, i], labeling, mask=mask, fill=np.nan)
plot_hemispheres(surf_lh, surf_rh, array_name=grad, size=(1200, 400), cmap='viridis_r',
color_bar=True, label_text=['Grad1', 'Grad2'], zoom=1.55, color_range=(-0.3, 0.3))
HI, Cool toolbox! I'm not able to set the color_range option for visualization in python. The following line works. plot_hemispheres(surf_lh, surf_rh, array_name=grad, cmap='viridis_r', color_bar=True, label_text=label_text)
But adding color_range= (-0.3, 0.3 ) gived vtk related errors.
