Hi,
Can someone please explain how to import EEG files recorded from a BioRadio using BioCapture software?
currently, I import as .mat format and it asks to specify one channel which has EEG recording. How can I import all the EEG recording channels?
What is the file extension to be used to import data to brainstorm?
Thanks in advance
The file format used by this software is not supported yet in Brainstorm. This is something we could add if you had access to .m files that can read this file into Matlab.
Otherwise, it looks like you can export your recordings as CSV files, and these ones could probably be imported into Brainstorm (after maybe removing a few columns or rows).
But you are talking about .mat files? How did you create these files?
This is the Matlab file format, which is nothing more but a collection of Matlab variables, it is not a "file format" for saving EEG recordings. If you try to import a .mat file into Brainstorm, the only option that you'll get offered is to read one of these variables, which is supposed to contain all the data (a matrix of values with dimensions [Nchannels x Ntime] or [Ntime x Nchannels]). For other configurations (eg. one variable for each channel, like it seems to be the case with what you describe), you would need to reorganize the .mat file before being to load it into Brainstorm (by concatenating the recordings for all the channels for instance).
You would probably lose less time by exporting your recordings as .csv files, especially if you are not experienced with Matlab programming.
Thank you for the valuable insight. .csv format was already tried but didn't work. But I edited the variables in the .mat as you mentioned and this time it took all my EEG channels. Appreciate the support and quick response.
