Re^3: Torsion angle PES scan using DLC

Hi,

this is because the conversion from internals to Cartesians
did not converge at one of the intermediate points. Firefly
has better conversion routine so your sample works just fine
with it.

This does not prevent one from running the PES scan, but it does force us to separate it in several smaller scans with ndisp1=5 each.
