Hi all, operating system: Windows 10 Trying to remove the bad stretches/interference/noise in the EEG signal. This is the current plot. [image] Have seen mne document for handing and rejecting bad channels for meg and eog data. I need to perform this for the eeg data. This is how my data loo…

Hello, almost all the information on bad channel removal and ICA that is being demonstrated on MEG data in our tutorials should apply to EEG data as well. So you can basically do the same, just feed in EEG instead of MEG data. Best wishes, Richard

Hello richard, I have tried these two links. But, it’s not working for me. As I don’t have the events data in my dataset. All the links use the events and only reject the bad stretches. https://mne.tools/stable/auto_tutorials/preprocessing/15_handling_bad_channels.html https://mne.tools/stable/a…

Hello, [image] Star: In my dataset all I have is the 14 channels and the labels to those 14 channel. are you saying you have continuous data without any events? Thanks Richard

Hello, No, This how my dataset looks. [image] Totally 5 labels for each task (writing, resting etc…). Thanks

I don’t understand your question then… I also don’t understand why you’re always showing your data as a CSV file (?). :thinking: I thought you’d successfully imported it into MNE?

Sorry I showed it to get the context for events. Yes I have imported it into MNE and created a raw array using the following and have also saved it in .fif incase. info = mne.create_info(ch_names, ch_types=ch_types, sfreq=sampling_freq) raw = mne.io.RawArray(data, info) raw.save('data.fif',overwr…

[image] Star: But then when I tried using mne.find_events and mne.Epochs . I am getting ValueError: Could not find event data Well, it seems you’re not creating a stim channel then… that’s required by find_events(). Or you just have to create the events array manually, which would then al…

I have a stim channel, but the “label” column in the csv is becoming the stim channel. [image] Is that right? If yes, then I have 4 labels totally but when I print the event id I am getting only 2. [image] But then again when I use mne.read_events I am getting this error. TypeError: fname mus…

[image] Star: If yes, then I have 4 labels totally but when I print the event id I am getting only 2. [image] Event codes must be >0 to be recognized; you seem to have -1 and probably 0. So you need to change this before you create the RawArray.

[image] richard: Event codes must be >0 to be recognized; you seem to have -1 and probably 0. So you need to change this before you create the RawArray. [image] Star: [image] This result is after converting them only. The label values are now 1,2,3&4. not -1,0,1,2. It’s only detecting …
