Hello AMBER developers/community,

I am working on AMBER distance restraints for a DNA system and came across
the CPPTRAJ rst command documentation:

https://amberhub.chpc.utah.edu/rst/
<https://amberhub.chpc.utah.edu/rst/?utm_source=chatgpt.com>

I wanted to ask if anyone would be open to discussing how this script can
be utilized for DNA structural studies.

I also want to confirm the unit of force/force constant used for rk2 and rk3.
Is it in *kcal mol⁻¹ Å⁻²*, as used in AMBER NMR-style restraints?

Any guidance or examples for DNA systems would be very helpful.

Regards,
Manasa
