Aspen.invoke('InitFromArchive2', 'C:\Users\ASPENPC\Desktop\a7777\77777.apw') 
Aspen.visible = 1;
data = Aspen.Application.Tree.FindNode("\Data\Properties\Parameters\Binary Interaction\NRTL-1\Input\VAL1\NRTL\MEA H2O").value
% i can't get aspen data only this nodepath

I want to connect aspen properties with MATLAB. like this:

AspenProperties.Application.Tree.FindNode("\Data\Properties\Analysis\BINRY-1\Output\Prop Data\PROPTAB\VAPOR MOLEFRAC BENZENE 2").value

But its showing an error: Dot indexing is not supported for variables of this type.

Please help me out

the output is as follows:

found tree as far as "\Data\Properties\Analysis\BINRY-1\Output\Prop Data\PROPTAB\VAPOR MOLEFRAC BENZENE 2" but no further

methods available for further exporation:

I had a slight mistake in the output. The proper output would have reported

found tree as far as "\Data\Properties\Analysis\BINRY-1\Output\Prop Data\PROPTAB\" but no further

parts = string({'Data' 'Properties' 'Analysis' 'BINRY-1' 'Output' 'Prop Data' 'PROPTAB' 'VAPOR MOLEFRAC BENZENE 2'});
oldcurrent = '\';
found_something = false;
ended_early = false;
for idx = 1 : length(parts)
   thistree = "\" + strjoin(parts(1:idx), "\");
   currentnode = AspenProperties.Application.Tree.FindNode(thistree);
   if isempty(currentnode); ended_early = true; break; end
   found_something = true;
   oldcurrent = currentnode;
end
if found_something
    if ended_early
        fprintf('found tree as far as "%s" but no further\n', oldcurrent);
    else
        fprintf('found the complete tree "%s"\n', thistree);
    end
    fprintf('methods available for further exporation:\n');
    methods(oldcurrent)
else
    fprintf('did not find any node at all, not even "%s"\n', thistree);
end
