Paper in question is:-
Enter the Matrix: Factorization UncoversKnowledge from Omics https://www.cell.com/trends/genetics/fulltext/S0168-9525(18)30124-0
Lead author, Dr Elana Fertig tweeted a link to their paper yesterday.
HOWEVER, the paper clearly states:- "This is an open access article under the CC BY license (http://creativecommons.org/licenses/by/4.0/)".
As such, why is it paywalled????
Historically, Elsevier are very slow in fixing errors like this.
