<div dir="ltr"><div><div><div><div><div><div>Hi all,<br></div>I used net station to export my 128-channel data as .raw format with and without exporting reference channel (which is Cz in my case). That is, I had two .raw files. <br>
<br>Then when I opened them in eeglab, it did not recognize the reference channel as Cz (automatically) for both files. Both files showed they had 128 channels. I expect that the file with the reference channel would show it has 129 channel (with Cz). <br>
<br></div>Next, my head model has location information about Cz, so I declared Cz as my reference channel (through GUI "set reference"). The eeglab main window showed that the reference was set to Cz. But when I plotted the data, the figure did not show Cz. Again I expect the channel number would increase to 129 and the plot would show a flat line indication Cz is the reference channel.<br>
<br></div>Finally, I could add Cz to the data by re-referencing to average (through GUI re-reference | add current reference channel back to data)<br><br></div>Can someone explain this to me?<br></div>Thank you so much for the help!<br>
