Can you please share a small example dataset?
Zip together some file that can allow us to reproduce exactly this error:
- A few data files that if placed in FilesA/FilesB produce this error (try with a small number of files)
- The channel file(s) associated with these data files
Thanks
Ok fine.
Where I send you a link for get the data ?
Thanks
Julien
Thank you for the example files.
I tested them on my computer and it works:
It looks like you work on MacOS, and I suspect that you haven't compiled the library. I made the instructions more explicit in the tutorial:
https://neuroimage.usc.edu/brainstorm/Tutorials/Decoding#Download_and_installation
I added a test to make the error message more explicit than what you got:
https://github.com/brainstorm-tools/brainstorm3/commit/aab58620804c95da9e31f327f3b8b3b04b8aced1
Perfect, you were fully right ! After having compiled the library, I had a nice result decoding result.
Thanks a lot for your help and this very nice process.
Last question : is there a significant value for decoding accuracy ? 80 - 90 %? I guess this is user's "choice" ?

Hi Jungju,
To establish statistical significance in decoding results, you still need to do statistics because high classification values can still arise by chance. See for example https://www.sciencedirect.com/science/article/pii/S0165027015000114
I use permutation tests in my work, when having multiple subjects and each subject contributes one decoding time course.
Best,
Dimitrios
