Is it possible to merge multiple BrainObj? #60

Closed iPsych closed 4 years ago

iPsych commented 4 years ago

Is it possible to merge multiple BrainObj? For example, build two separate BrainObj (Left and Right hemisphere) and merge them, or several Objs from label volumes.

Yes, it should be possible using the SceneObj, which is made to superimpose objects. Something like that :

sc = SceneObj()
b_obj_1 = BrainObj('custom_1', ...)
b_obj_2 = BrainObj('custom_2', ...)

sc.add_to_subplot(b_obj_1)
sc.add_to_subplot(b_obj_2)

sc.preview()

See examples using the scene

Thanks. I am wondering merge objects in GUI. It seems not possible to put multiple BrainObj in Brain, right? For example, Insular, Left hemisphere, and Cerebellum separately.

Below works,

from visbrain.gui import Brain
vb = Brain(brain_obj=b_obj)
vb.show()

But below doesn't works.

from visbrain.gui import Brain
vb = Brain(brain_obj=[b_obj, b_obj2])
vb.show()

Yes, the GUI only supports a single brain object
