Definition

The simple base pair opening for the A:B base pair. This is an earlier implementation providing only opening, full set of simple base pair parameters is availble via CV:NASBPP.

IMPORTANT: It is critical that the A and B bases are not separated during simulation due to imaging of DNA chains into the simulation box. Use ether topjoinmol from CATs to merge both chains into a single molecule or use the correct value of iwrap in sander or pmemd.

Specification

Section name: NASBO

Key Type Default Description




name string unique CV name
group_a mask atoms for the base A ring
reference_a string name of the file with the reference structure in the XYZ format, the structure must have the same number of atoms as the group group_a
group_b mask atoms for the base B ring
reference_b string name of the file with the reference structure in the XYZ format, the structure must have the same number of atoms as the group group_b
skip_mass_test logical .false. if .true. it does not control atom masses between the system and loaded reference structures

Keys in bold are mandatory.
