Methods before results

It’s great that, in a step towards improved reproducibility, the Nature journals are removing page limits on Methods sections:

To allow authors to describe their experimental designs and methods in enough detail for others to interpret and replicate them, the participating journals are removing length restrictions on Methods sections.

But couldn’t they include the Methods section in the pdf for the article? For example, consider this article in Nature Genetics; the Methods section is only available in the html version of the paper. The PDF says:

Methods and any associated references are available in the online version of the paper.

Methods are important.

  • They shouldn’t be separated from the main text.
  • They shouldn’t be placed after the results (as so many journals, including PLoS, do).
  • They shouldn’t be in a smaller font than the main text (as PNAS does).
  • They certainly shouldn’t be endnotes (as Science used to do).

Supplements annoy me too

I love supplemental material: authors can give the full details, and they can provide as many supplemental figures and tables as they want.

But supplements can be a real pain.

  • I don’t want to have to click on 10 different links. Put it all in one document.
  • I don’t want to have to open Word. Put text and figures in a PDF.
  • I don’t want to have to open Excel. Put data in a plain text file, preferably as part of a git repository with related code.

At least supplements are now included at the journal sites!

This paper in Bioinformatics refers to a separate site for supplemental information:

Expression data and supplementary information are available at
http://www.rii.com/publications/2003/HE_SDS.htm.

But rii.com doesn’t exist anymore. I was able to find the supplement using the Wayback Machine, but

  • The link in the paper was wrong: It should be .html not .htm
  • The final version on Wayback has a corrupted PDF, though one can go back to previous versions that are okay.

I like Genetics and G3

Genetics and G3 put the Methods where they belong (before the results), and when you download the PDF for an article in Genetics, it includes the supplement. For a G3 article, the supplement isn’t included in the article PDF, but at least you can the whole supplement as a single PDF.

For example, consider my recent Genetics articles:

If you click on “Full Text (PDF),” you get the article plus the 3 supplemental figures and 23 supplemental tables in the former case, and article plus the 17 supplemental figures and 2 supplemental tables in the latter case.
