Hi, I export PSD Welch file to excel. It generates a table of frequency x electrode.
I chose the Physical: U2/Hz in the Welch's pipeline editor. I would like to confirm with you the unit used for the numbers in this table please

Thank you

Hi @mmbriand

The export function: export_timefreq does not change the units of the PSD. The output is in the same units as they are computed (here U2/Hz). You can check also the PSD function here : bst_psd.m

HI @tmedani, yes, that was what I thought. However, my team want me to double check what does the U refer to? I know it usually means unit, but it is more often reported as Volt. So I just want to make sure, what that means for Brainstorm. I am sorry for the basic question.

Here the u refers to micro (because it looks like the greek mu), making uV microvolt
