 Here `@mda:` indicates that the `MDAnalysis` language is used, whereas `@mdt:` indicates that the `mdtraj` language is used. Notice that these languages typically select atoms in order. If you want to specify a different order, you can chain definitions as in `g3` above (compare with `g2`). Selections can be also chained with standard PLUMED selections (see `g6`).
