[FieldTrip] calculate ERD / ERS

[tiago lopes]

Hi,i am using the toolbox fieldtrip to calculate ERD / ERS in different groups. However, i do not know if I should use a relative or absolute power density in function cfg.baselinetype.
I am using the following script,
cfg                                 = [ ];cfg.method                     = 'wavelet';cfg.width                        = 7cfg.output                        = 'pow'cfg.foi                           =4:0.2:30;cfg.toi                           = -.68:0.01:1.5;cfg.keeptrials                ='no';cfg.baseline                    =[-0.4 -0.1];cfg.baselinetype            ='relative';         (I do not know if I should use a relative or absolute.)TFRtot                          = ft_freqanalysis(cfg, date)TFRtotal                       = ft_freqbaseline(cfg, TFRtot);

Can anyone help me with this problem please?
