Overview

Encapsulates the affine transform between an section-image pixel position to a location in the specimen volume (tsv) and vice versa (tvs). A 2-D affine transform is defined by 6 parameters: the first 4 parameters represents the matrix part in row-major order and the last 2 parameters the translation part. These values have been generated by the informatics data processing pipeline. See pipeline overview for more details.

tvs_00 (Float) —

specimen volume to section-image transform parameter 00
tvs_01 (Float) —

specimen volume to section-image transform parameter 01
