<div dir="ltr">I have a few questions regarding frequency analysis using wavelets.<div><br></div><div>1. Is it possible to z-score the TF spectrograms? Is so how and where should I specify the baseline?</div><div>2. Before grand averaging ERFs, the pipeline has 'megrealign' to make sure all sensors from multi subject are matched. However, why is this not performed before grand averaging time-frequency data since the powspctrm is specific to each channel?</div>
<div>3. Is combineplanar a necessary step before any grand averaging i.e. ERF or TFR? I am using neuromag data, so can I perform grand averaging and statistics without combineplanar? </div><div>4. Fieldtrip only reads neuromag FIF files that has been processed through maxfilter. There are times when there is a need not to use maxfilter, is there a work around?</div>
