Please note that there is only a single stiweb_lambda potential which contains all required lamdba parameters. The number of parameters for the stiweb_lambda potential depends on the total number of atom types.

makeapot

The example potential can be generated with the following makeapot command:

makeapot -n 2 -i stiweb
