   Hi all,

   I encounted an error reported by Matlab when I was running the kspaceFirstOrder3DC() in the toolbox example,'example_cpp_running_simulations.m' with setting example_number = 3 (i.e. testing case 3), and I also got a similar error while testing case 2. I am using the toolbox in Mac and Matlab2016a. I tried to run the the program would stop in the middle with the error:

   case 3 error:
   /bin/bash: ./kspaceFirstOrder3D-OMP: Permission denied
   Error using h5readc
   Unable to open file. Filename may be
   corrupt or have unsupported characters.

   Error in h5read (line 58)
   [data,var_class] =
   h5readc(Filename,Dataset,start,count,stride);

   Error in kspaceFirstOrder3DC (line 348)
   Nx = h5read(output_filename, '/Nx');

   Error in example_cpp_running_simulations
   (line 131)
   sensor_data =
   kspaceFirstOrder3DC(kgrid,
   medium, source, sensor,
   input_args{:});

   case 2 error:
   Error using h5readc
   Unable to open file. Filename may be
   corrupt or have unsupported characters.

   Error in h5read (line 58)
   [data,var_class] =
   h5readc(Filename,Dataset,start,count,stride);

   Error in example_cpp_running_simulations
   (line 122)
   sensor_data.p_final =
   h5read([pathname
   output_filename], '/p_final');

   Is the error because of the Mac system? Or does anyone have a solution to this error?

   Many thanks in advanced.

   hello Frankie,

   I encounted the same error as yours, which reported by Matlab when I was running the kspaceFirstOrder3DC() in the toolbox example,'example_us_beam_patterns.m'. I am using the toolbox in Ubuntu 14.04 and Matlab2014b. So I think it might be a common erros. Error is reported as follow:

   /bin/bash: ./kspaceFirstOrder3D-OMP: Permission denied
   Error using h5readc
   The HDF5 library encountered an error and produced the following stack trace information:

   H5FD_sec2_open unable to open file: name = '/tmp/kwave_output_data12-Oct-2016-14-26-59.h5',
   errno = 2, error message = 'No such file or directory', flags = 0, o_flags = 0
   H5FD_open open failed
   H5F_open unable to open file: time = Wed Oct 12 14:27:00 2016
   , name = '/tmp/kwave_output_data12-Oct-2016-14-26-59.h5', tent_flags = 0
   H5Fopen unable to open file

   Error in h5read (line 58)
   [data,var_class] = h5readc(Filename,Dataset,start,count,stride);

   Error in kspaceFirstOrder3DC (line 347)
   Nx = h5read(output_filename, '/Nx');

   Error in example_us_beam_patterns (line 178)
   sensor_data = kspaceFirstOrder3DC(kgrid, medium, transducer, sensor, input_args{:});

   I hope someone would solve this problem.

   thanks in advanced.

   hello Frankie,

   I have solved this problem by adding +x permission

   chmod +x ./kspaceFirstOrder3D-OMP
   chmod +x ./kspaceFirstOrder3D-CUDA

   Hope this will be useful for you.

   Hi Frankie,

   Unfortunately at this stage we do not support Mac OS. If you are comfortable with compiling C++ codes, you could download the C++ source codes. It will require some edits (compiler directives etc), but people have told me they have got it to work in the past.

   Hope that helps,

   Brad.

   Hi Yufeng,

   Thank you for the solution. It seems like your permission modification commands are for Unix system. Do you happen to know the equivalent for win 7?

   Thank you in advanced!
