• Label 2035:right insula

Preprocessing on the training data consisted of:

• n4 bias correction,

• denoising,

• brain extraction, and

• affine registration to MNI. The input T1 should undergo the same steps. If the input T1 is the raw T1, these steps can be performed by the internal preprocessing, i.e. set doPreprocessing = TRUE

Value

list consisting of the segmentation image and probability images for each label.
