PMFLib offers two variants of the base-pair parameters, local and simple, which both are fully compatible with [https://x3dna.org/ 3DNA]. They differ in the definition of the y-axis and the procedure to calculate six base-pair parameters, ''i.e.'', Shear, Stretch, Stagger, Buckle, Propeller, Opening. | |||
The simple version is provided by [[CV:NASBPP|NASBPP]]. It uses an explicitly defined y-axis and Buckle, Propeller, Opening parameters are calculated as dihedral angles. | |||
The local version is provided by [[CV:NALBPP|NALBPP]]. It uses a y-axis derived from the superimposed reference frames of two nucleobases and all parameters are calculated using the CEHS scheme. | |||
The collective variable [[CV:NASBO|NASBO]] implements simple Opening only and thus it should be a little bit computationally faster than [[CV:NASBPP|NASBPP]]. | |||

Base-Pair Parameters
PMFLib offers two variants of the base-pair parameters, local and simple, which both are fully compatible with 3DNA. They differ in the definition of the y-axis and the procedure to calculate six base-pair parameters, i.e., Shear, Stretch, Stagger, Buckle, Propeller, Opening.
The simple version is provided by NASBPP. It uses an explicitly defined y-axis and Buckle, Propeller, Opening parameters are calculated as dihedral angles.
The local version is provided by NALBPP. It uses a y-axis derived from the superimposed reference frames of two nucleobases and all parameters are calculated using the CEHS scheme.
The collective variable NASBO implements simple Opening only and thus it should be a little bit computationally faster than NASBPP.
Base-Pair Step Parameters
PMFLib offers two variants of the base-pair step parameters, local and simple, which both are fully compatible with 3DNA. They differ in the definition of the y-axes, i.e., Shift, Slide, Rise, Tilt, Roll, Twist.
The simple version is provided by NASSTP. It uses explicitly defined y-axes of two base pairs and all parameters are calculated using the CEHS scheme.
The local version is provided by NALSTP. It uses y-axes derived from the superimposed reference frames of four nucleobases and all parameters are calculated using the CEHS scheme.

Reference coordinates for nucleobase rings are provided in the following table:
| Nucleobase | Ring Atoms | y-axis (BPP) | y-axis (STP) | File |
