Hi,

I'm trying to use fiff\_read\_bad\_channels.m from the mne matlab toolbox.  
Does anyone know what "node" means? Or is there another way to read bad  
channel from a fif file into matlab? Thanks.

\>\> help fiff\_read\_bad\_channels  
[bads] = fiff\_read\_bad\_channels(fid,node)

Read the bad channel list from a node if it exists

fid - The file id  
node - The node of interest

Hi Yingal,

You can also read it from a raw or evoked file after loading it onto  
matlab. If, for example, you call the loaded file "raw", type  
"raw.info.bads" and you will see the bad channels.

Best,
