BF_CHEBYSHEV_RATIONAL_FULL_INFINITE
This is part of the ves module
It is only available if you configure PLUMED with ./configure –enable-modules=ves . Furthermore, this feature is still being developed so take care when using it and report any problems on the mailing list.

Rational Chebyshev basis functions on a full-infinite interval

Compulsory keywords
ORDER The order of the basis function expansion.
MINIMUM The minimum of the interval on which the basis functions are defined.
MAXIMUM The maximum of the interval on which the basis functions are defined.
MAP_PARAMETER Constant map parameter that defines the interval on which is the bias is active (should match the width of the function to be expanded).
Options
DEBUG_INFO ( default=off ) Print out more detailed information about the basis set. Useful for debugging.
NUMERICAL_INTEGRALS

( default=off ) Calculate basis function integral for the uniform distribution numerically. Useful for debugging.

CENTER the location of the center of the Hermite functions. By default it is 0.0
