I’m using trakem2 to segment dendrites and axons from EM images. I have segmented entire dendrites including spines and would now like to divide an existing arealist into smaller segments which represent the spines only.
Is there a way to do this to existing arealists? Ideally something that will let me select a portion of an existing area list and give it a new arealist.
I realise I can segment them manually and create new arealists myself, but this will be time consuming for new and existing dendrites. I’ve included screenshots of how I manually segmented the existing area.
Is there anything else that may be of help?
