Deformation profile is a metric first discribed in the paper “New metrics for comparing and assessing discrepancies between RNA 3D structures and models.” (RNA. 2009 Oct;15(10):1875-85. doi: 10.1261/rna.1700409. )

A full implementation can be found at github, maintained by Chichau

RNA-Puzzles Assessment consider all the “Basic Assessment Metrics”, Deformation profile and “Mean of Circular Quantities”.
