Currently I am analyzing group MEG data recorded using 152 axial gradiometers during tactile stimulation tasks. The axial gradiometer data were planar-transformed to template sensor positions. The power spectrum in the sensor level was calculated using ft_freqanalysis and combined using ft_combineplanar.<o:p></o:p></span></p><p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p><p class="MsoNormal"><span lang="EN-US">For group analysis of the spectral powers, I tried to compare different options for the </span>‘<span lang="EN-US">baselinetype</span>’<span lang="EN-US"> field in ft_freqbaseline. But when I called the ft_freqbaseline with cfg.baselinetype = </span>‘<span lang="EN-US">zscore</span>’<span lang="EN-US">, I received the following error message:<o:p></o:p></span></p><p class="MsoNormal"><span lang="EN-US"> <o:p></o:p></span></p><p class="MsoNormal"><span lang="EN-US" style="color:#002060">Error using ft_checkopt (line 156)<o:p></o:p></span></p><p class="MsoNormal"><span lang="EN-US" style="color:#002060">the value of the option "baselinetype" is invalid<o:p></o:p></span></p><p class="MsoNormal"><span lang="EN-US" style="color:#002060">Error in ft_freqbaseline (line 77)<o:p></o:p></span></p><p class="MsoNormal"><span lang="EN-US" style="color:#002060">cfg = ft_checkopt(cfg, 'baselinetype', 'char', {'absolute', 'relative', 'relchange', 'normchange', 'db', 'vssum'}); <o:p></o:p></span></p><p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p><p class="MsoNormal"><span lang="EN-US">Is the </span>‘<span lang="EN-US">zscore</span>’<span lang="EN-US"> option available for the baselinetype in the ft_freqbaseline? As in the above error message, the </span>‘<span lang="EN-US">zscore</span>’<span lang="EN-US"> option is not included in the ft_checkopt, while it is included in the subfunction [data = performNormalization]. But then, the </span>‘<span lang="EN-US">stdVals</span>’<span lang="EN-US"> used in the zscore computation [data = (data-meanVals)./stdVals], was not defined anywhere in the performNormalization subfunction.
