I am quite confused now. I think I get what you are talking about with "unit gain" and "unit noise-gain” as defined by Sekihara, as much as I can make out at least with out having the book you refer to (on the bright side I now know what to nag my boss for). I suppose I was a quite mis-leading with what I had in my last email, by which, what I actually did was use the LCMV beamformer to make lead fields to calculate the virtual sensors (see <a href="http://www.fieldtriptoolbox.org/tutorial/shared/virtual_sensors" class="">http://www.fieldtriptoolbox.org/tutorial/shared/virtual_sensors</a>). Of note, your link to the discussion list is now even more useful. I am using centimeters and a single shell head model. The wiki says "<span style="text-align: justify; widows: 1; background-color: rgb(255, 255, 255);" class=""><span style="line-height: 22.5px;" class="">CMV beamformer spatial filter for the location of interest will pass the activity at that location with unit-gain”. From your email, I suspect then that the output would be in </span></span>Am units. I am a little concerned though that both my output, and the field trip wiki shows values ranging ~ -3 -> 3 (e-4, i.e. mAm not nAm). Or instead would the units be in <span style="white-space: pre-wrap;" class="">T/(Am) (if I apply the 1e4 unit conversion). Sorry for not being better at this, I think I do need those books you were mentioning...</span></font></div><div style="text-align: justify; widows: 1;" class=""><span style="white-space: pre-wrap; font-size: 14px;" class=""><font face="Calibri" class=""><br class=""></font></span></div><div style="text-align: justify; widows: 1;" class=""><span style="white-space: pre-wrap; font-size: 14px;" class=""><font face="Calibri" class="">Best,</font></span></div><div style="text-align: justify; widows: 1;" class=""><span style="white-space: pre-wrap; font-size: 14px;" class=""><font face="Calibri" class="">Russ</font></span></div><div class=""><font face="Calibri" style="font-size: 14px;" class=""><br class=""></font></div><div class=""><font face="Calibri" style="font-size: 14px;" class=""><br class=""></font></div><div class=""><font face="Calibri" style="font-size: 14px;" class=""><br class=""></font></div><div class=""><font face="Calibri" style="font-size: 14px;" class=""><br class=""></font></div><div class=""><font face="Calibri" style="font-size: 14px;" class=""><br class=""></font><div><blockquote type="cite" class=""><div class=""><font face="Calibri" style="font-size: 14px;" class="">On Sep 11, 2015, at 12:40 PM, Marc Lalancette <<a href="mailto:marc.lalancette@sickkids.ca" class="">marc.lalancette@sickkids.ca</a>> wrote:</font></div><font face="Calibri" style="font-size: 14px;" class=""><br class="Apple-interchange-newline"></font><div class=""><span style="font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: 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; font-size: 14px;" class=""><font face="Calibri" class="">mformer with unit gain would have Am units.</font></span></div></blockquote></div><br class=""></div></body></html>
