   Hi,

   When I change kspaceFirstOrder3D() to kspaceFirstOrder3DC(), Matlab reports the following error:

   Error: File "C:\Users\m066760\AppData\Local\Temp\kwave_output_data05-Aug-2013-10-40-57.h5" could not be created!

   Thanks

   Hi Bo.

   This is an interesting error. Could you check, if MATLAB succeeded with the creation of the kwave_input_data_.....h5 file. If it did, than it means, you can write into your TEMP folder (no user permission issues). Otherwise, there's something wrong with your TEMP folder.

   If the input file was created and the output one could not be, then I'd bet that you don't have enough disk space on your C disk drive. Could you check this please?

   Hi Jiri,

   The h5 file was created and I can find it in the TEMP folder. There is a lot of disk space in the drive.

   Could the default location be changed, at least to try a different folder to see if the same error pops up.

   Thanks for your reply.

   Hi Bo,

   Yes, you can change the default location of the C++ I/O files.
   Open file kspaceFirstOrder3DC.m and locate

   date_string = getDateString;
   input_filename = [tempdir 'kwave_input_data' date_string '.h5'];
   output_filename = [tempdir 'kwave_output_data' date_string '.h5'];

   Then you can change tempdir variable to point at a different location.

   Jiri,

   Thanks for your response. The problem is solved. There was a strange user right policy on the computer.

   Dear Jiri:
   I encountered similar issue, please help to check, and I've created another dir(c:\test) for it, but still the same:

   Error using h5readc
   The HDF5 library encountered an error and produced the following stack trace
   information:

   H5FD_windows_open unable to open file, errno = 2, error message = 'No
   such file or directory'
   H5FD_open open failed

   [data,var_class] = h5readc(Filename,Dataset,start,count,stride);

   It seems to be ok to run in my PC, I will figure it out and sorry for the confusion.

   Hi,

   I've encountered the same problem:
   The HDF5 library encountered an error and produced the following stack trace information:

   H5FD_sec2_open unable to open file: name = 'D:\test\kwave_output_data13-Jun-2016-14-28-05.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 = Mon Jun 13 14:28:32 2016
   , name = 'D:\test\kwave_output_data13-Jun-2016-14-28-05.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');

   I can't cope with the reason why the input file is written in the right directory but not the output file.

   I use the SS3 first download link for kspaceFirstOrder3DC, on matlab 2015b and I've already tried the option 'DataPath':

   input_args = {'DataPath','D:\test' };

   Still it doesn't work.

   Would you have a solution for me ?
   Thank you,

   Mat

   Hi Mark,
   this has something to do with the window permissions.

   Could you try a simple trick and let me know.

   1. create an input file, say d:\test\input.h5
   2. copy the binary into the same folder
   3. run commandline and type kspacefirstorder3D-OMP -i input.h5 -o output.h5

   and then let me know what happened?

   Cheers,
   Jiri

    Are you using MATLAB 2020a? If so, this is a known issue. I'm working with Mathworks at the moment on a solution. In the meantime, it should work if you using 2019b and earlier.

    Hi Brad,

    I am using 2019b and I am also getting a similar error.

    Error using h5readc
    The filename specified was either not found on the MATLAB path or it contains
    unsupported characters.

    Error in h5read (line 66)
    [data,var_class] = h5readc(Filename,Dataset,start,count,stride);

    Error in kspaceFirstOrder3DC (line 569)
    Nx = h5read(output_filename, '/Nx');

    Error in kspaceFirstOrder2DC (line 89)
    sensor_data = kspaceFirstOrder3DC(varargin{:});

    Error in v06 (line 114)
    sensor_data_2D = kspaceFirstOrder2DC(kgrid, medium, source, sensor,
    input_args{:});

    ......................................................

    I tried using the method which has been posted on the forum (making changes to h5writeatt) but even that didn't help here.

    Can you suggest something else which can be done?

    Thanks

    Hi arunima0111
    I don't think this is the same problem. This looks more like Matlab not being able to find a C++ binary, or the file doesn't have +x permission on linux.

    Hi Bradley,

    Thank you for making this toolbox openly accessible. Is the problem raised above by Ruben (regarding the fatal error in MATLAB 2020a) resolved, since I am getting the same issue?

    Please find it below:

    Hi Anirudh,

    See the discussion here. Note, if you're using a later version of MATLAB (>=2021), you don't need the patch from the MATLAB side any longer.

    Brad.

    Hi,

    I got the same problem. And my system is Linux. The MATLAB has created the kwave_input_data_.....h5 file in the /tmp. But it did not have the output...h5. The disk space is enough. How can i fix it?

    Thanks,
    Tina

    Hi,
    my PC does the something similar to Tina's, it has a problem with creating the output. It's as if MATLAB doesn't find the folder because it puts another folder in the path that doesn't exist.

    For example, the first time pinted:

    Unable to open '/home/MATLAB/Add-Ons/...'

    and then I though it was because all Matlab stuff should be in the same folder, so I created the MATLAB folder and moved all the things there and I tryed again. The result was the same:

    Unable to open '/home/MATLAB/MATLAB/Add-Ons/...'

    How could I fix it?

    And I have some addicional questions; on Linux it's better to uses binaries or source files for C, and if I use sources, how?

    Thank you in advance,
    Maria

    Hi,

    I've gone through all the threads, and it looks like all the changes are implemented in MATLAB (2024b) and k-Wave 1.4, but I'm still encountering this issue. Also, I can't locate the Temp folder.

    Error using h5readc
    Unable to open 'C:\Users\toshi\AppData\Local\Temp\kwave_output_data29-Mar-2025-14-31-12.h5'. File or folder not found.

    Error in h5read (line 95)
    [data,var_class] = h5readc(Filename,Dataset,start,count,stride);

    Error in kspaceFirstOrder3DC (line 569)
    Nx = h5read(output_filename, '/Nx');

    Error in kspaceFirstOrder2DG (line 76)
    sensor_data = kspaceFirstOrder3DC(kgrid, medium, source, sensor, input_args{:});

    Error in simSPA (line 36)
    sensor_data = kspaceFirstOrder2DG(kgrid, medium, source, sensor, input_args{:});

    Error in OpticalSimulation (line 299)
    simSPA(vmcmesh, vmcmedium, vmcboundary, vmcoptions, kgrid, medium, ...)

    Thank you.
