Our previous research has shown mu (lack of mu suppression) to have frontal, temporal, central and limbic aspects that are disrupted bilaterally due to multiple connectivity deficits across these regions. What you see centrally at the surface is the result of these multiple phenomena. So, having multiple components is not a problem to collapse it is the reality of what you are studying.</div><div class=""><br class=""></div><div class="">Rob</div><div class=""><br class=""><div><blockquote type="cite" class=""><div class="">On Jan 19, 2016, at 12:33 PM, Jenson, Dave <<a href="mailto:djenson1@uthsc.edu" class="">djenson1@uthsc.edu</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><div style="font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px; direction: ltr; font-family: Tahoma; font-size: 10pt;" class="">All,<br class=""><br class="">Does anyone know how to merge components from an ICA decomposition into a single component? I am running a study on the sensorimotor mu rhythm, and I have a few subjects for whom ICA produces multiple potential components. At the moment I am choosing the best component per subject based on scalp map, spectra, and dipole location. However, I still have a few subjects for whom there is no clear winner. I don't want to lose statistical power by excluding a component that represents the sensorimotor mu, but also don't want to disproportionately weight some subjects over others at the study level by including multiple components. Is there a way to 1) merge components or 2) overcome this problem in a different manner?<br class=""><br class="">-Dave Jenson<br class=""><br class=""></div><span style="font-family: Helvetica; font-size: 14px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px; float: none; display: inline !important;" class="">_______________________________________________</span><br style="font-family: Helvetica; font-size: 14px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px;" class=""><span style="font-family: Helvetica; font-size: 14px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px; float: none; display: inline !important;" class="">Eeglablist page:<span class="Apple-converted-space"> </span></span><a href="http://sccn.ucsd.edu/eeglab/eeglabmail.html" style="font-family: Helvetica; font-size: 14px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px;" class="">http://sccn.ucsd.edu/eeglab/eeglabmail.html</a><br style="font-family: Helvetica; font-size: 14px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px;" class=""><span style="font-family: Helvetica; font-size: 14px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px; float: none; display: inline !important;" class="">To unsubscribe, send an empty email to<span class="Apple-converted-space"> </span></span><a href="mailto:eeglablist-unsubscribe@sccn.ucsd.edu" style="font-family: Helvetica; font-size: 14px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px;" class="">eeglablist-unsubscribe@sccn.ucsd.edu</a><br style="font-family: Helvetica; font-size: 14px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px;" class=""><span style="font-family: Helvetica; font-size: 14px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px; float: none; display: inline !important;" class="">For digest mode, send an email with the subject "set digest mime" to<span class="Apple-converted-space"> </span></span><a href="mailto:eeglablist-request@sccn.ucsd.edu" style="font-family: Helvetica; font-size: 14px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px;" class="">eeglablist-request@sccn.ucsd.edu</a></div></blockquote></div><br class=""></div></body></html>
