m-file (level 2) s-function - dynamic frame data setting

[prankmunky]

I am now having problems when running my simulation with an m-file s-function that i have created. I recieve the following block error when i simulate:


Source 'registration/M-file (level-2) S-Function' cannot have dynamic frame data setting for its output port 1. All sources should explicitly set all their output ports to be frame or non-frame

Here's my code (its pretty simple so i guess I'm missing somethimg):

function loadVTKpoints(block)
% Level-2 M file S-function for loading movie
% (image edge detection demonstration).
% Copyright 1990-2004 The MathWorks, Inc.
% $Revision: 1.1.6.1 $

setup(block);

function setup(block)

%% Register parameters
block.NumDialogPrms = 1;
block.DialogPrmsTunable = {'Tunable'};

%% Register number of ports
block.NumInputPorts = 0;
block.NumOutputPorts = 2;

%% Setup functional port properties
block.SetPreCompOutPortInfoToDynamic;

block.OutputPort(1).DatatypeID = 0; % double
block.OutputPort(1).Complexity = 'Real';
%block.OutputPort(1).SamplingMode = 'Sample';

block.OutputPort(2).DatatypeID = 5; % uint32???
block.OutputPort(2).Complexity = 'Real';
%block.OutputPort(2).SamplingMode = 'Sample';

%ALSO HGOW WOULD I SET THE DIMENSIONS OF THE ARRAY IF IT IS RETRIEVED
%WITHIN MY FUNCTION
%block.OutputPort(1).Dimensions = size(points);
block.OutputPort(1).Dimensions = -1;
block.OutputPort(2).Dimensions = 1;

%% Register methods
%%IVE TRIED BOTH OUTPUT AND OUTPUTNONFRAME
block.RegBlockMethod('Outputs', @OutputNonFrame);
%block.RegBlockMethod('Outputs', @Output);

%endfunction

function OutputNonFrame(block)
CT_input_directory = block.DialogPrm(1).Data;
vtk_file = textread(CT_input_directory,'%s','delimiter','=" ','whitespace','');
points_num = str2double(vtk_file(12)); %Number of points
points_end = 14-1+3*points_num;

index=0;
index = (14oints_end);
points = str2double(vtk_file(index));

clear vtk_file;

block.OutputPort(1).Data = points;
block.OutputPort(2).Data = cast(size(points),'int32');

%endfunction
