Abstract.
Provide a general introduction to the topic and a brief nontechnical summary of your main results and their implication.
Text length and formatting. Attention to the following details can help expedite publication if we invite a revision after external review.
- Articles: an abstract of approximately 150 words, unreferenced; main text of no more than 5,000 words and 10 display items (figures, tables). As a guideline, Articles allow up to 70 references. Section headings should be used and subheadings may appear in 'Results'. Avoid 'Introduction' as a heading.
Methods.
The Methods section appears in all online original research articles and should contain all elements necessary for interpretation and replication of the results. Methods should be written as concisely as possible and typically do not exceed 3,000 words but may be longer if necessary. We encourage you to deposit any step-by-step protocols used in your study in
Protocol Exchange, an open resource maintained by NPG. These protocols are linked to the Methods section upon publication.
