I am not sure what mathworks decided to change this time. In any case, please feel free to fork the project on github, make the fixes, and send a pull request.

@kavita: Have you downloaded the dependencies.tar, extracted and added it to your matlab path ? It can be found here: https://github.com/johnyf/openstreetmap/releases

In there you will find the renamed xml2struct_fex28518 function. The rename is to avoid name conflicts with the bioinformatics toolbox (removing that from your installation is not recommended).

The original error that you see did not relate to the bioinformatics toolbox, since it couldn't find xml2struct_fex28518, not xml2struct.

The persistency of xml2struct in matlab's path may be due to caching (e.g., compare `which` with `hash` in a bash shell). Perhaps after restarting matlab it won't find xml2struct any more. In any case, it is not the cause for the error.

Just select "Export" at the top left and zoom in enough so that it won't complain on the export pane (opens on the left after you click "Export") that the area is too large to be exported. Then hit the blue "Export" button on the left pane, and that will download the ".osm" file that contains the XML data you need.

Material opacity is supported by IDTF. You can try experimenting with changing the alpha value from 1.0 to less than 1.0, i.e., undoing this change:

Hi,

I downloaded all the dependencies and also the map.osm file from github, and I tried running the usage_example.m
I got an error:
Error using bioinfoprivate.opttf
which is an error with the Bioinformatics_Toolbox

Hence, I commented out line 38,39,40,41 and 55 in the route_planner.m file, to make sure that it only runs the part not for Bioinformatics_Toolbox.

However, when I run the example again, it shows:
Parsed OpenStreetMap given.
Found 370 common nodes.
Connectivity matrix contains 1350 nonzero elements.
Although the unique ones were 226.
Warning: No route found by the route planner. Try without road directions.
> In route_planner at 59
In usage_example at 47

Bounds: xmin = -73.8573, xmax = -73.8337, ymin = 40.7788, ymax = 40.7974

and also 2 windows like this:

What did I do wrong? I am supposed to get something like this: http://www.mathworks.com/matlabcentral/fileexchange/screenshots/9670/original.jpg

right?

Delighted with this. However, not yet working with the Updated Graphics System on the 2014b Prerelease (can't see why). Is anyone else interested in trying this on the Prerelease?

Undefined function 'isnan' for input arguments of type
'matlab.graphics.GraphicsPlaceholder'.

Error in u3d_pre_quivergroup (line 63)
sh(isnan(sh) ) = [];

Error in fig2u3d (line 198)
[quiver_vertices, quiver_edges, quiver_colors] = u3d_pre_quivergroup(ax);
