[Eeglablist] Regarding Pre-processing pipeline

Dear Kumar,

can I cite the webpage ?

I don't think citing a website is valid in scientific communication. Check
the journal's policy.

Warning: do not interpolate channels before running ICA


Is it okay to proceed further ignoring this message ?

ICA can 'usually' tell the right rank of the data, so I would say it's ok.
If you have a concern, use 'pca', 16 if your number of channels BEFORE
INTERPOLATION is 16 to explicitly tell ICA to use rank of 16.
