Hello Brainstorm community,
I am trying to export the following preprocessed-raw-continuous recording consisting of 15 EEG channels, 2 EOG channels (EXG1 and EXG2) and 3 EMG channels (EXG3-5) into pdf pages of 30-sec epochs for sleep stage scoring and list some related questions. At the moment the EXG1-5 channels are classified within Brainstorm channel editing as EEG but they are actually EOG and EMG channels. This is so that EEG-EOG-EMG channels can be viewed on one page without opening a new window for each channel type.
I know that there is a way to specify channel type (as in EEG, EOG and EMG) using the following process "Import > Channel file > Set channels type".
However is there a Brainstorm process to change the NAME of the channel? I need to change the name of the EOG and EMG channels and was wondering if there is a fast way to do this (the EXG1-5 channels into something like left and right eye and chin muscle).
At the moment you will see at the top right-hand corner (circled in red) that the channels are being viewed at 51uV. Is there a way to specify this differently for each channel?
As in EEG channels get 50uV, EOG and EMG at 25 uV.
What would be the best way to export this continuous recording into 30-sec epochs?
I've tried "Import in database" specifying that the recording be split into 30-sec epochs.
This does not work fully as the epochs do not contain EOG and EMG (which I already specified to be EEG in the continuous recording). They do not appear because through the "Import in database" process, Brainstorm automatically reclassified them as EOG-NO-LOC.
Therefore how would you overcome this problem?
And subsequently, what would be the best way to export all 30-sec epochs into one file so that the end result is one file which I can flick through like a book so that each page equals a 30-sec epoch.
Many thanks in advance.
