Error using load export_matlab

I calculated the source results and then tried to export in matlab , but it alsways get errors like the following, could you help me to solve this?

Also, I have tried to import the mat file from the path, also, it get some erroe\rs, error using load

The fact that load() also gives errors suggests that there is a problem with the file, either it does not exist, or it is corrupted. The last could be caused by stopping Brainstorm when it was writing the file.

  1. Verify that the file indeed exist, if so
  2. Can you re-compute those sources?

yeah, I have calculated agian, and I could double click to open the source map, but could load the file to read. I calculate threee times.

If the file opens when you double-click it.

Can you try to load() with the path that is return with right-click the file, then File > Copy file path to clipboard?
