This process performs a length-parameterization of sulcus meshes. This is useful to study the morphology of sulci and localize features on them.
The sulcus needs to have been identified and labelled automatically or by hand before, and is modeled by a triangular mesh. The result is a coordinate field that localize any point on the mesh of the sulcus with respect to its two extremities. An important constraint is that the sulcus must have only one piece, which is fairly restrictive. So far it has been used on the Central Sulcus and on the Superior Temporal Sulcus after a specific adaptation.
The process produces a coordinate field that can be displayed on the sulcus as well as a text file that contains the depth curve, and the sulcal profile, two descriptors of the sulcus shape. From the sulcal profile it is possible to compute the position of the hand-knob.
The latest version of the process is in the BrainVisa Cortical Surface Toolbox, under the Anatomy category and is called: Sulcal Parameterization 2015. It has been described in the following publication:

Below is a short tutorial to run this process
