    403403Fixed parameters can be specified by using any of the 'parameter' type structures. You must specify the type of parameter first, before listing the name, starting value, and state. These structures are read by '''nuiscomp''', '''nuismin''', and '''nuissyst'''

    405 TYPE_parameter  NAME   VALUE  STATE

    413413- **VALUE** : Starting value for the dial. In general for RW engine parameters this is given in terms of 1-sigma variations away from the nominal, so that VALUE=0.0 is the nominal generator value. For everything else, like normalisation parameters, this value is in units of the true value.
    414414
    415 - **STATE** : State of the dial. This should always be left as FIX as this is the only support option for the time being.

    418415Multiple parameter structures can be listed in the nuisance card file to make comparisons with many model parameters changed at once.

    427424**Example 1** : Fixed GENIE RW 'MaCCQE' to +1 sigma
