# minnorm_parameters_cb

## (Toolbox/minnorm_parameters_cb.m in BrainStorm 2.0 (Alpha))

### Function Synopsis

    hf = minnorm_parameters_cb(action,GUI,hf);

### Help Text

    MINNORM_PARAMETERS_CB - Minimum Norm GUI setup and execution
     function hf = minnorm_parameters_cb(action,GUI,hf);
     function hf = minnorm_parameters_cb; % Build and return handle to figure
     function minnorm_parameters_cb(action); % switchyard
     function minnorm_parameters_cb(StudySubject,GUI,hf); % initialize
     Called with no action, it will build the GUI window using rap_parameters.fig
     action may be either a string or a StudySubject structure
     StudySubject must be a proper find_brainstorm_structure
     In the initialization, GUI must contain the fields
      GUI.Segment, vector of column indices to process in the data matrix
      GUI.Rank, the rank of the signal subspace to use
      GUI.DataName, the referentially qualified filename of the data set
      GUI.ChannelFlag, +1 for each channel to be used
