Question about MIN keyword in ALPHARMSD (PLUMED 2.9.3 vs 2.10.x)

[Chenfeng Zhang]

Hi,

I’m trying to use the collective variable ALPHARMSD with the MIN option, and I’m getting an error in PLUMED 2.9.3. My input line is:

helix: ALPHARMSD RESIDUES=all TYPE=OPTIMAL NOPBC MIN BETA=10

The error message I get is:

ERROR for keyword MIN in action ALPHARMSD with label helix : keyword BETA is compulsory for this vessel.

I checked the PLUMED 2.10.x manual, and it looks like MIN is no longer listed as a keyword for ALPHARMSD. Has this functionality been removed or changed in newer versions?

Thanks for your help!

Best wishes,

Chenfeng
