Bug in mcxplotshapes

[ChenJY-L]

Dear Prof. Fang Qianqian:
MCX is an amazing repo.
There is a bug in mcxpreview.m dealing with "Grid", "Box" and "subgrid".
The originate of box doesn't change acroing to my settings.
cfg.shapes=['{ "Shapes":['... '{"ZLayers":[[1,2,2]]}, {"Box": {"Tag":3, "O":[50,50,50], "Size":[50,50,10]}}' ... '] }'];
Because of the code in

mcx/utils/mcxplotshapes.m

Lines 72 to 83 in 80b5794

	case {'Grid', 'Box', 'Subgrid'}
	if (strcmp(sname{1}, 'Grid') && ~isempty(hseg))
	delete(hseg);
	hseg = [];
	end
	obj = shp.(sname{1});
	if (isfield(obj, 'Tag'))
	tag = obj.Tag;
	end
	gridsize = obj.Size;
	[no, fc] = latticegrid([0 obj.Size(1)], [0 obj.Size(2)], [0 obj.Size(3)]);
	hseg(end + 1) = plotmesh(no * voxelsize, fc, 'facealpha', 0.3, 'linestyle', '-', 'facecolor', 'none', varargin{:});

I tried to fix it using these code.
Thanks for this amazing work again.
Best wishes.

case {'Grid','Box','Subgrid'}
      if(strcmp(sname{1},'Grid') && ~isempty(hseg))
          delete(hseg);
          hseg=[];
      end
      obj=shp.(sname{1});
      if(isfield(obj,'Tag'))
          tag=obj.Tag;
      end
          
      gridsize=obj.Size;
      if(isfield(obj, 'O'))
          [no,fc]=latticegrid([obj.O(1) obj.Size(1)+obj.O(1)],[obj.O(2) obj.Size(2)+obj.O(2)],[obj.O(3) obj.Size(3)+obj.O(3)]);
      else
          [no,fc]=latticegrid([0 obj.Size(1)],[0 obj.Size(2)],[0 obj.Size(3)]);
      end
      hseg(end+1)=plotmesh(no*voxelsize,fc,'facealpha',0.3, 'linestyle', '-', 'facecolor','none', varargin{:});
