So for the lab I work in, I'm trying to display some data, as I've done here. It's SEEG/ECOG data. However, when I display the data on the cortex, for some reason, it shows that there's no units. How do I change this?
Thanks!

The problem is not with the display, it is probably with the data.
The values should be in the range of the microV (~10e-6 Volts) or milliV (~10e-3 Volts), while here they seem to go up to 50 Volts. This is therefore not interpreted as Volts, Brainstorm guesses it must be something else.
If you looks at the iEEG recordings time series, there are probably no units either.
Where did you import this data from?
Hello Francois,
So sorry for not responding till now. I've been absolutely swamped with midterms and other schoolwork.
I imported this data from a folder containing the data that the lab I work in sent to me to analyze.
I then took the average of all the data and that is what I have plotted. I'm not exactly sure how to pull up those raw data points to show here, but I will try to do that and send that as an update if I figure it out. I think I'd have to use Matlab for that, right?
On Brainstorm, it's showing up like this.
Thank you!
Sincerely,
Arul

My question was more precisely: In what file format were initially the recordings coming from?
Brainstorm is supposed to adjust the units automatically for most known file formats.
If you are using more manual import procedures, then you need to pay attention to store all the values in international units (Volts and not microV).
