Hi
I am not sure what you are asking exactly. You can of course threshold the images before calling find_the_biggest (with fslmaths). You can also do all of it in matlab or python and bypass find_the_biggest.

However, when I provide the masks for both of these, the hand knob mask doesn’t end up iin the biigest.nii.gz file. Is it because it’s the part of the M1 which shows correctly? Is there any way to do it then, or how could I approach do it otherwise? The file seeds_to_hand_knob area has a correct output so there are definitely tracks going from my seed to hand knob strip.
