Hi everyone,

I am new to MEG and have little experience, I want to ask is the channel showed in the figure a bad channel? or It’s alright and I should keep it?

Thanks for your help!

Dear Hailin,

You need to adjust the amplitude and time resolution to inspect the data quality visually, as mentioned in this tutorial:

Here the tutorial set the axes resolution, but I am used to use Amplitude→Set amplitude scale, and use ~700fT. Remember to cancel the auto resolution (unselect the AS button).

For time resolution, I recommend drag the red time bar below the data plot to ~10 seconds. Then you may review the signal page by page.

Hope this helps,
