Step 1
The profile/time series wave that you want to constrain must be stored under root:SoFi:Reference_pr or root:SoFi:Reference_ts:raw, respectively. In addition, this wave is required to have the same length as your PMF profile/time series input. Use the “treat external data” panel to achieve this.
Step 2
After setting your general PMF settings, first set a seed value for the factor that you want to constrain under “model matrices”. Use the option “from vector”, where you can select the wave prepared under step 1.
Step 3
Set your constraint(s), e.g. an a-value.
