If not, is there any other option to compare plv between conditions</div><div><br></div><div>I use the following code:</div><div><br></div><div>cfg=[];</div><div>cfg.statistic='depsamplesT';</div><div>cfg.method='analytic';</div><div>cfg.parameter='plvspctrm';</div><div>cfg.channel={'all'}; % 5 channels -> 10 channelcmb</div><div>cfg.tail=0;</div><div>cfg.alpha=0.05;</div><div>cfg.ivar=2;</div><div>cfg.uvar=1;</div><div>cfg.frequency = [10 50];</div><div><br></div><div>cfg.design=[1:12,1:12;ones(1,12),ones(1,12)*2];</div><div><br></div><div>[stats_fus_vi]=freqstatistics(cfg,plv_fu{:},plv_vi{:}); </div><div><br></div><div>I get the information:</div><div><div>renaming parameter 'plvspctrm' into 'powspctrm'</div><div>selected 5 channels</div><div>selected 201 time bins</div><div>selected 21 frequency bins</div><div><br></div><div>As I don't get any error message, I assume this works fine so far but I'm confused about what is computed here: Is "powspctrm" used instead of "plvspctrm" (i.e. the test is computed between power estimates instead of phase locking values)? Why are only 5 channels selected instead of the 10 combinations?</div><div><br></div><div>I already tried renaming "plvspctrm" and "labelcmb" to "powspctrm" and "label" but then I get an error message, as freqstatistics selects 20 channels.</div><div><br></div><div>Thanks a lot for any advise</div><div><br></div><div>Julian</div><div><br></div></div><br><div>
