Error opening nwb files

I updated the NWB downloader, and it will automatically update the NWB library to the version currently supported by Brainstorm.
https://github.com/brainstorm-tools/brainstorm3/commit/93ad6b827c173a87962b137a6bdbdcbcde7c6308

However, I can't get the function nwbRead() to read the example files you suggested...
I set Brainstorm to use the last stable release of the matnwb library (https://github.com/NeurodataWithoutBorders/matnwb/tree/v2.2.5.0), and if I try to use it to read these NWB files, I get and error. If I use the current master branch, I get a different error...
I'm not sure what to do with that.

Are you familiar with this file format?
Can you read them with other programs in Matlab? Using this matnwb library?

@mpompolas Could you help us with this?
