Merge different epochs or trials


When I tried brainstorm to import the .ds file I downloaded from the public dataset, I found that there were many epochs of the same length in the file. This caused me trouble with processing and exporting this data, and I had to export many files. How can I combine these epochs when importing, or combine multiple trials that appear after importing into one trial?

Thank you,


Hi Mengqi,

By default Brainstorm imports .ds folders as epoched recordings. It is necessary to manually change this to continuous recordings. More info in:
