Slightly off topic: Jabref complains about an enty like this one:
@Article{Okabe2014, ..... journal = {PLoS One}, year = {2014}, volume = {9}, pages = {e109693}, ..... What has to be used for the entry type instead of @Article{.. ?I am using biblatex/biber. I went through the JabRef help but did not find the relevant hint.
