clarifications for the use of the ZMAP

[AnnnaFiglioli]

I am a PhD student at the University of Palermo, I deal with geophysics in particular in seismology.
I started using the ZMAP software.
I encounter some problems, I hope that interfacing with you can solve them.
In particular, I wanted to ask you why I find errors trying to calculate the magnitude of completeness with other methods that are not maxcurvature.
I can't calculate anything ........... and it gives me a slew of errors.
This is one of the mistakes that lies ahead ...
Error using ZmapCatalog/sort
Too many output arguments.

Error in calc_McBest (line 12)
magnitudes = sort(magnitudes);

Error in calc_Mc>method_bestcombo (line 165)
[~, Mc95, Mc90] = calc_McBest(mags, binInterval);

Error in calc_Mc>@(C)method_bestcombo(C,binInterval) (line 68)
methodFun = @(C)method_bestcombo(C,binInterval);

Error in calc_Mc>do_calculation (line 144)
fMc = methodFun(mCatalog);

Error in calc_Mc>@(C)do_calculation(methodFun,C,mcCorrectionFactor) (line 127)
mcCalculator = @(C) do_calculation(methodFun, C, mcCorrectionFactor);

Error in XYfun.bvalgrid/Calculate/do_calculation (line 109)
Mc_value = mcCalculator(catalog);

Error in XYfun.bvalgrid>@(catalog)do_calculation(catalog,@calculate_noboot) (line 93)
obj.gridCalculations(@(catalog) do_calculation(catalog, @calculate_noboot));

Error in gridfun/doSinglefun (line 198)
returned_vals = fun(minicat);

Error in gridfun (line 118)
doSinglefun(fcn);

Error in ZmapGridFunction/gridCalculations (line 126)
] = gridfun( calculationFcn, obj.RawCatalog, obj.Grid, obj.EventSelector, obj.NodeMinEventCount
,numel(obj.CalcFields), 'noreshape' );

Error in XYfun.bvalgrid/Calculate (line 93)
obj.gridCalculations(@(catalog) do_calculation(catalog, @calculate_noboot));

Error in ZmapFunction/doIt (line 192)
obj.Calculate();

Error in XYfun.bvalgrid>@(varargin)obj.doIt(varargin{:}) (line 76)
zdlg.Create('Name', 'b-Value Grid Parameters', 'WriteToObj', obj, 'OkFcn', @obj.doIt);

Error in ZmapDialog/okDlg (line 980)
obj.OkFcn(); % call the function provided by the user upon dialog creation

Error in ZmapDialog>@(src,)obj.okDlg() (line 898)
'Callback',@(src,)obj.okDlg());

Error while evaluating DestroyedObject Callback.

If you can help me understand why I find these errors for all the techniques I would be grateful.

Are there a manual of ZMAP?
