Is it possible to find source localization with just raw EEG data? I don’t have BEM, I don’t know how to compute forward solution. I am trying to follow the tutorial below, but I am stuck.

I don’t have a forward solution file. I just have raw EEG data with channels

Thank you!!!
I have montage information in my raw data
I tried to make forward solution as below:
fwd = mne.make_forward_solution(raw.info, trans=trans, src=src,
bem=bem, eeg=True, mindist=5.0, n_jobs=1)
I got the following error:
RuntimeError: Missing EEG channel location

@gharshini maybe you forgot to set the montage for your raw
object? That is, the object doesn’t know about the locations of the EEG electrodes?
Please read this thread, and my answer at the end of it, it may solve your problem as well: Problems to interpolate channels in EEG
