Definition
The simple base pair parameters for the A:B base pair fully compatible with the 3DNA definition.
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: NASBPP
| 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 | |
| group_c | mask | atom defining origin of y-axis | |
| group_d | mask | atom defining end of y-axis | |
| parameter | string | type of parameter (one of): shear, stretch, stagger, buckle, propeller, opening | |
| 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.
