Defining collective variables and their properties

In the configuration file each colvar is defined by the keyword colvar, followed by its configuration options within curly braces: colvar { ... }. One of these options is the name of a colvar component: for example, including rmsd { ... } defines the colvar as a RMSD function. In most applications, only one component is used, and the component is equal to the colvar.

The full list of colvar components can be found in Section 13.4, with the syntax to select atoms in Section 13.3. The following section lists several options to control the behavior of a single colvar, regardless of its type.
