In my study, I have to check that my participants did not move their fingers during the task. To do so, I used two external electrodes (namely, EX3 and EX4) to record muscular activity. I would need to inspect my data visually on continuous data after a bipolar montage between these two electrodes.</div><div class=""><br class=""></div><div class="">I first tried to use appenddata but it is not convenient for what I am looking. Then, I tried to use ft_lateralized but, if I am right, it’s for averaged data, which is not my case since I need to check continuous data. I finally tried cfg.operation but I am not sure if why I am doing is correct for the purpose I have. In addition, I have an error indicating that <font color="#e32400" class="">This function requires unknown data as input</font>.</div><div class=""><br class=""></div><div class=""><div style="margin: 0px; font-size: 10px; font-family: Courier;" class="">cfg = [];</div><div style="margin: 0px; font-size: 10px; font-family: Courier;" class="">cfg.dataset = <span style="color: #b245f3" class="">'P4_IB_2.bdf'</span>;</div><div style="margin: 0px; font-size: 10px; font-family: Courier;" class="">cfg.preproc.hpfilter = <span style="color: #b245f3" class="">'yes'</span>;</div><div style="margin: 0px; font-size: 10px; font-family: Courier;" class="">cfg.preproc.hpfreq = 10;</div><div style="margin: 0px; font-size: 10px; font-family: Courier;" class="">cfg.channel = {<span style="color: #b245f3" class="">'EX3'</span>, <span style="color: #b245f3" class="">'EX4'</span>};</div><div style="margin: 0px; font-size: 10px; font-family: Courier;" class="">E1 = <span style="color: #b245f3" class="">'EX3'</span></div><div style="margin: 0px; font-size: 10px; font-family: Courier;" class="">E2 = <span style="color: #b245f3" class="">'EX4'</span></div><div style="margin: 0px; font-size: 10px; font-family: Courier;" class="">cfg.operation = <span style="color: #b245f3" class="">'E1-E2'</span>;</div><div style="margin: 0px; font-size: 10px; font-family: Courier;" class="">data = ft_math(cfg, E1, E2);</div><div style="margin: 0px; font-size: 10px; font-family: Courier;" class="">cfg.ylim = [-150 150];</div><div style="margin: 0px; font-size: 10px; font-family: Courier;" class="">cfg.blocksize = 5;</div><div style="margin: 0px; font-size: 10px; font-family: Courier;" class="">cfg.viewmode = <span style="color: #b245f3" class="">'butterfly'</span>;</div><div style="margin: 0px; font-size: 10px; font-family: Courier;" class="">ft_databrowser(cfg, data);</div><div style="margin: 0px; font-size: 12px; font-family: Courier; min-height: 14px;" class=""><br class=""></div></div><div style="margin: 0px; min-height: 14px;" class="">I would strongly appreciate if some of you had some recommandations about what is the best method that I could use or, if using cfg.operation is the best method, how I could solve the error message.</div><div style="margin: 0px; min-height: 14px;" class=""><br class=""></div><div style="margin: 0px; min-height: 14px;" class="">Thank you in a dance for your time!</div><div style="margin: 0px; min-height: 14px;" class=""><br class=""></div><div style="margin: 0px; min-height: 14px;" class="">Best, </div><div style="margin: 0px; min-height: 14px;" class=""><br class=""></div><div style="margin: 0px; min-height: 14px;" class="">Emilie</div><div style="margin: 0px; font-size: 12px; min-height: 14px;" class=""><br class=""></div><div class=""><br class="">
