Hi Maryam,

Do you know about autoreject: http://autoreject.github.io/? Does it do the
job for you?

> Hi all,
> I am using mne to process some EEG data which I have collected from

> channels are noisy in some part of the epoched data and I want to reject
> them. What I understand from MNE is that I can reject bad channels based on
> peak-to-peak amplitude by setting reject parameter when using "mne.Epochs"
> to epoch the data. This is very cool, but this rejects the whole epoch
> containing this noisy channel and throws out the data of good channels as
> well. The other possible way is to mark a channel as "bad" and then epoch
> the data from the remaining channels. The problem of this latter way is
> that some channels are noisy only in some part of the experiment and not in
> all the session.
> My question is if there is any way to reject only bad channels in an epoch
> (instead of rejecting the whole epoch or rejecting a channel in the whole
> session)?
