10 Simple Steps to Writing a Scientific Paper

3. Storyboard the Figures
Figures are the best place to start, because they form the backbone of your paper. Unlike you, the reader hasn't been living this research for a year or more. So, the first figure should inspire them to want to learn about your discovery.
A classic organizational approach used by writers is "storyboarding" where all figures are laid out on boards. This can be done using software like PowerPoint, Prezi, or Keynote. One approach is to put the vision statement on the first slide, and all of your results on subsequent slides. To start, simply include all data, without concern for order or importance. Subsequent passes can evaluate consolidation of data sets (e.g., forming panel figures) and relative importance (e.g., main text vs. supplement). The figures should be arranged in a logical order to support your hypothesis statement. Notably, this order may or may not be the order in which you took the data. If you're missing data, it should become obvious at this point.
4. Write the Methods Section
Of all the sections, the methods section is simultaneously the easiest and the most important section to write accurately. Any results in your paper should be replicable based on the methods section, so if you've developed an entirely new experimental method, write it out in excruciating detail, including setup, controls, and protocols, also manufacturers and part numbers, if appropriate. If you're building on a previous study, there's no need to repeat all of those details; that's what references are for.
One common mistake when writing a methods section is the inclusion of results. The methods section is simply a record of what you did.
The methods section is one example of where knowing the journal is important. Some journals integrate the methods section in between the introduction and the results; other journals place the methods section at the end of the article. Depending on the location of the methods section, the contents of the results and discussion section may vary slightly.
