Hi Francois,
Thank you very much for your prompt reply. I have tried to install 2.4.0 to 2.4.2 version, and all versions produce the same results. I am wondering is it possible to be a read/write permission issue? i.e. Brainstorm could not access the file because of reading restriction. I have tried to use terminal to enable permission but still could not fix the problem. My matlab ver output is the following:
