[Eidors Help] Error when using Netgen to build Single Plane Models

[李. <li...@ma...>]

Hi everyone,

I'm trying to run the"Build Single Plane Models with Netgen"in my PC with a 64 bit version of windows and netgen 5.0 installed. The version of EIDORS is 3.6 and the Matlab is R2009b. The code is as follow:
% Build model% $Id: build_single_plane01.m,v 1.4 2007/09/21 19:07:47 aadler Exp $ % Choose Parameterselectrodes_per_plane= 16;number_of_planes= 1;refine_electrodes= 10;tank_radius= 15;tank_height= 10;electrode_width = 0.5;electrode_height= 0.5;rect_or_circ_electrode= 'C';  fname ='tank_mdl'; first_plane_starts= tank_height/(number_of_planes+1);height_between_centres = first_plane_starts; [fmdl,centres] = create_tank_mesh_ng( ...   tank_radius, tank_height, ...   rect_or_circ_electrode, ...   log2(electrodes_per_plane), ...   number_of_planes, ...   first_plane_starts, ...   height_between_centres, ...   electrode_width, electrode_height, ...   fname, refine_electrodes  ); % The msz file was created here can be reused latermsz_file= [fname, '.msz'];stim_pat= mk_stim_patterns(electrodes_per_plane, number_of_planes, ...

However,when I started to run the code,there always got an error message. The error information shows as follows:

??? Error using ==> ng_mk_fwd_model>construct_fwd_model at 65

Failed to find all the electrodes




Error in ==> ng_mk_fwd_model at 39

fwd_mdl= construct_fwd_model(srf,vtx,simp,bc, name, ...




Error in ==> create_tank_mesh_ng at 210

tank_mdl= ng_mk_fwd_model( meshfn, centres, ...




Error in ==> Netgen_2D at 20

[fmdl,centres] = create_tank_mesh_ng( ...




 
Is something wrong with the EIDORS or the code? I am looking forward to your reply.

Thank you for your help!

Best regards,
