Reviewing EEG issue

Bugs
1

I import my EEG data as a matlab variable (data points x channel number).
I subsequently import the appropriate montage for those 33 channels of data.
There is no time information with these data, I just know that there are 256 samples/sec
My problem comes when I want to review the data.
The complete data are presented in the EEG graph, and in the Brainstorm control box the Page Setting controls are ‘grayed out’. And with maybe 10 minutes of data presented on a single screen it is not possible to review the waveforms in detail.
I would like to review my data in 10s pages and ‘page through’ the data to check it, but I can’t seem to work it out.
I managed it with the sample data set provided, but can’t seem to get it working with my data.
Any ideas?

thanks

With the menu “Import MEG/EEG”, you will always get files that are considered as “epoched”, saved in one single .mat file that are read and displayed in one single block. In this case, the menus to scroll in the files are not available.

You can convert your imported files back to “continuous” binary files with the popup menu “File > Review as raw”.

To learn how to use Brainstorm, start by following the introduction tutorials, at least until #19:
http://neuroimage.usc.edu/brainstorm/Tutorials

Then you can read the EEG-specific tutorial, that gives additional details on how to process EEG recordings:
