It¹s also worth noting that in Connectome Workbench we moved away from the deformation map file as it enforces a particular resampling of the data as well (not just a data transformation). Instead we use the deformed and target spheres to store the registration and this allows for choice in different resampling approaches whenever resampling is performed.

A description of the file¹s content is available at http://brainvis.wustl.edu/CaretHelpAccount/caret5_help/file_formats/file_for mats.html#deformationMapFile. Essentially, the deformation map file defines a resampling of one surface triangular mesh to another. For each vertex in the target surface, it identifies the corresponding location in the source surface using barycentric coordinates. A barycentric coordinate contains three vertex indices that form a triangle and the weights define the location within the triangle.
