tutorial: using multiple data sources

I am working on 'setting up your model' tutorial and I can't find the files for the petten data. Please help, thank you

% obtain ArcGIS data from AHN25
[x1 y1 z1 info] = arc_asc_read('P:\1002266-xbeach\XBeachToolbox\data\petten\ahn25_petten.asc', 'zscale', 1);

Hi Claire,

First of all, sorry for this late reply.

We have been having a few messages from people with similar errors. It seems related to the Matlab toolbox rather than XBeach. The tutorials you are referring to are pretty much outdated and we have started the process of renewing them.

That may still take a few weeks/months so for now I would recommend to use the manual (http://oss.deltares.nl/documents/48999/49476/XBeach_manual_Kingsday.pdf) for information/inspiration and try to set up a simple simulation for your case, rather than trying to reproduce the tutorials.

Apologies for the confusion.

Cheers,
Arnold

Hi
I am learning how to simulate the beach evolution with hard layers. I also try to generate the input files as the manual. However, I could not find the datasets in the tutorial such as vaklodingen_petten.mat, ahn25_petten.asc, ahn5_petten.asc, ahn25_seawall.asc, So could you send a copy to me? My email zwzhang@mail.dlut.edu.cn

% obtain ArcGIS data from AHN25
[x1 y1 z1 info] = arc_asc_read('P:\1002266-xbeach\XBeachToolbox\data\petten\ahn25_petten.asc', 'zscale', 1);

% obtain ArcGIS data from AHN5 (higher resolution, smaller area)
[x2 y2 z2 info] = arc_asc_read('P:\1002266-xbeach\XBeachToolbox\data\petten\ahn5_petten.asc', 'zscale', 100);

% obtain preprocessed Vaklodingen data
S = load('P:\1002266-xbeach\XBeachToolbox\data\petten\vaklodingen_petten.mat');
x3 = S.x; y3 = S.y; z3 = S.z;

% merge the three bathymetries in order
[x y z] = xb_grid_merge('x', {x1 x2 x3}, 'y', {y1 y2 y3}, 'z', {z1 z2 z3});

% obtain ArcGIS data from AHN25 containing the non-erodable layers
% (seawall) and interpolate on merged grid
[x4 y4 z4 info] = arc_asc_read('P:\1002266-xbeach\XBeachToolbox\data\petten\ahn25_seawall.asc', 'zscale', 1);
ne = ~isnan(xb_grid_interpolate(x4, y4, z4, x, y));

% plot the merged bathymetry
pcolor(x, y, z); shading flat; axis equal; colorbar; snapnow;

Thanks Very Much
