[FieldTrip] baseline normalizing

[mubeen afzal]

Hi all,

In brainstorm there is option of baseline normalizing (zscore or db or other methods) the timeseries epochs/trials of interest before frequency analysis allowing visual comparisons and further frequency analysis of the normalized epochs

The normalization function function [freq] = ft_freqbaseline(cfg, freq) doesnt allow normalizing a freq output dimord structure with chan_freq derived using 'mtmfft' method

I get this error message -

"the call to "ft_freqanalysis" took 1 seconds
the input is freq data with 21 channels, 191 frequencybins and no timebins
Error using ft_freqbaseline (line 146)
unsupported data dimensions: chan_freq"

Is there a way around this?

Thanks all.

Mubeen
