We would need an example dataset to reproduce this error.

Please try to reproduce this error with a minimal set of files: 2 files in FilesA, 2 files in FilesB.
Zip the 4 files + the channel file together, upload it somewhere, and post the download link here.

Thanks

Thank you for sending these files. However, I don't know what to do with them.
Instead, please share the files as they are in the Brainstorm database (files channel_...mat and data_...mat).
To see where a file is located on the hard drive: right-click on the file > File > Show in file explorer.

Please include screen captures of :

  • the Brainstorm window showing the data files you sent me highlighted in the Brainstorm database explorer + the same files selected the in Process2 tab
  • the Pipeline Editor window showing the options of the test process

And make sure that this produces exactly the error message you sent previously.

Thanks

The files you sent are name "1.mat" and "2.mat", and contain only a matrix data.
These are not files coming from the Brainstorm database.
I can't reproduce the error your reported with the files you sent. These are NOT Brainstorm files.

If you want me to be able to test anything, please send me the 4 data files (4x data_...mat) + the corresponding channel files (channel_...mat) as they are in the Brainstorm database.
Total: 5 or 6 files.

Hi professor,
thanks for your reply
I extracted 4 data files and 1 channel file from the Brainstorm database as you had said in previous conversations. I put the download link below.

Thank you for the example files.

The problem is that your data was saved in single instead of double precision, and that bst_meanvar.m does not accept single precision inputs.

I pushed two fixes:

Update Brainstorm to get these fixes.
Note that we do not recommend importing data from partly pre-processed files in .mat format, but rather recommend always importing EEG from the original RAW files and do the pre-processing in Brainstorm.

Hi professor,
I resolved the errors by reimporting raw data and doing pe-processing in updated Brainstorm
thanks for your reply
