It looks to me that either the C++ code crashed or you're out of disk space and the file was not closed correctly. </p> <p>Jiri </p> http://www.k-wave.org/forum/topic/another-unable-to-open-file-post#post-5847 Sun, 12 Mar 2017 05:36:01 +0000 ad000000 5847@http://www.k-wave.org/forum/ <p>Hi All,<br /> I notice that there are several posts with errors when running the C code from within the m-file. Has anyone got this to work? I'm running Win7 with Sandybeach CPU. I notice that some posts mention the setting of permissions, but I have no idea how to do that in Windows.<br /> Thanks!</p> <p>Error using h5readc<br /> The HDF5 library encountered an error and produced the following<br /> stack trace information:</p> <p> H5FD_windows_open unable to open file, errno = 2, error<br /> message = 'No such file or directory'<br /> H5FD_open open failed<br /> H5F_open unable to open file: time = Sat Mar 11<br /> 22:49:21 2017<br /> , name =<br /> 'C:\Users\T410s\AppData\Local\Temp\kwave_output_data11-Mar-2017-22-48-57.h5',<br /> tent_flags = 0<br /> H5Fopen unable to open file</p> <p>Error in h5read (line 59)<br /> [data,var_class] = h5readc(Filename,Dataset,start,count,stride);</p> <p>Error in kspaceFirstOrder3DC (line 347)<br /> Nx = h5read(output_filename, '/Nx');</p> <p>Error in example_us_beam_patterns (line 178)<br /> sensor_data = kspaceFirstOrder3DC(kgrid, medium, transducer, sensor,<br /> input_args{:}); </p>
