I have separate ROIs for the two sides of the hippocampus and am trying to combine them using nilearn. So far I’ve managed to binarize them using nilearn.image.math_img :
R_mask_img = load_img("…")
R_mask = math_img(‘img > 0’, img=R_mask_img)
and when I plot the individual sides, they look great, but when I try to combine them using the code:
bilat_mask = nilearn.masking.intersect_masks([L_mask, R_mask], threshold=0) and plot the result, it only shows a region on the left side of the brain (regardless of which order I put the masks in mask_img list).
Can someone give me insight into what might be going on? Thanks!
