Overview

Encapsulates the affine transform between an specimen volume position to a location in the reference space (tvr) and vice versa (trv). A 3-D affine transform is defined by 12 parameters: the first 9 parameters represents the matrix part in row-major order and the last 3 parameters the translation part. These values have been generated by the informatics data processing pipeline. See pipeline overview for more details.
