Hi Roy,

I have pasted the relevant section from
http://www.fieldtriptoolbox.org/reference/ft_freqstatistics the lines that
would be applicable in your situation.


The configuration can contain the following options for data selection
    *cfg.channel     = Nx1 cell-array with selection of channels
(default = 'all'),
                      see FT_CHANNELSELECTION
<http://www.fieldtriptoolbox.org/reference/ft_channelselection> for
details*
    *cfg.avgoverchan = 'yes'* or 'no'                   (default = 'no')
