Nature Methods Formatting Requirements: Complete Author Guide

Nature Methods uses an unstructured abstract, consistent with all Nature Portfolio journals.

• Word limit: 150 words maximum
• Structure: Unstructured (single paragraph)
• Citations: Not allowed in the abstract
• Keywords: Not submitted by authors; assigned by editorial staff
• Abbreviations: Spell out at first use

The abstract should state the problem with existing methods, describe the new approach at a high level, and present the key performance metrics. For a methods paper, specific performance numbers are expected. Write "Our approach achieves 94% accuracy on the benchmark dataset, a 12-percentage-point improvement over the current standard" rather than "Our approach substantially outperforms existing methods."

Don't describe the biological application in detail in the abstract unless the method was developed specifically for that application. The abstract should sell the method, not the biology.

A detail that matters: Nature Methods abstracts frequently include a sentence about code/data availability (e.g., "The software is available at github.com/..."). This isn't formally required in the abstract, but editors favor it because it signals openness.

Nature Methods allows up to 6 display items (figures and tables combined) in the main text.

Figure specifications:

Extended Data: Up to 10 Extended Data figures or tables are allowed. These are peer-reviewed and appear in the published article alongside the main figures. They don't count toward the 6-item display limit. For methods papers, Extended Data commonly contains additional benchmarking results, parameter sensitivity analyses, and comparison metrics against alternative methods.

Supplementary Information: Beyond Extended Data, you can include Supplementary Information files (Supplementary Figures, Tables, Notes, Videos, Software). These are peer-reviewed but hosted as separate downloadable files. Supplementary Tables are often submitted as Excel files, which is preferred over embedding them as images.

For Nature Methods specifically, method comparison figures are expected to be fair and transparent. If you're benchmarking your method against alternatives, show results on the same datasets with the same evaluation metrics. Reviewers will check this carefully.

Schematic diagrams: Almost every Nature Methods Article includes a method overview schematic as Figure 1. This diagram should show the workflow or algorithmic pipeline clearly. Use consistent visual language. Don't mix different diagramming styles within a single figure.

Nature Methods uses the standard Nature citation style.

In-text citations: Superscript numbers, assigned sequentially as references first appear in the text. No brackets or parentheses. Multiple citations are separated by commas (e.g., "^1,2") and ranges use a hyphen (e.g., "^3-7").

Reference list format:

1. Smith, A. B., Johnson, C. D. & Williams, E. F. Title of article. Nat. Methods 22, 123-130 (2025).

Key formatting details:

• Author names: Last name, comma, initials without periods
• Use "&" before the last author
• Journal names abbreviated per ISO 4
• Volume in bold
• No issue numbers for most journals
• Page range in the format start-end
• Year in parentheses at the end
• DOIs encouraged but not required in the reference list

Nature Methods has a reference cap of approximately 50 for Articles, which is more generous than the main Nature journal (~30). This reflects the need to cite prior methods, benchmarking datasets, and validation studies. Reviews can go up to approximately 100 references.

The reference list appears before the Online Methods section. The document order is: main text, references, Online Methods, figure legends, Extended Data figures/tables.

Nature Methods uses a tiered supplementary system.

Extended Data (Tier 1): Up to 10 figures or tables. Peer-reviewed, published inline with the article. Use this for essential supporting data that strengthens the main findings but doesn't fit in the 6 display item limit. For methods papers, this typically includes additional benchmarks, robustness analyses, and cross-validation results.

Supplementary Information (Tier 2): Files that readers can download. This includes Supplementary Figures, Supplementary Tables (often as Excel), Supplementary Notes (for mathematical derivations or extended protocol descriptions), and Supplementary Videos. These are also peer-reviewed.

Source Data (Tier 3): Raw, unprocessed data underlying each figure. Nature Methods requires Source Data for all main figures and Extended Data figures. This is part of the journal's commitment to reproducibility.

Code and software: Nature Methods requires that all custom code described in the paper be deposited in a public repository (GitHub, GitLab, Zenodo, etc.) and assigned a persistent identifier (DOI via Zenodo or similar). A code availability statement is mandatory. The README in the repository should include installation instructions, example usage, and expected outputs. Reviewers will test your code.

Reporting Summary: All life sciences submissions must include a completed Nature Portfolio Reporting Summary. This covers statistical methods, data exclusions, replication details, and randomization procedures. The checklist is available from the Nature Portfolio editorial policies page.

Nature Methods doesn't require a formal cover page in the same way clinical journals do. However, the manuscript file must begin with specific elements.

Required opening elements:

• Title (concise, typically under 100 characters)
• Author names with superscript affiliation numbers
• Affiliations with full institutional addresses
• Corresponding author(s) with email addresses
• ORCID iDs for all authors (strongly encouraged, required for corresponding author)

What's NOT on the first page:

• Word counts (tracked by the system, not the author)
• Conflict of interest statements (entered separately in the submission system)
• Funding information (entered in the submission system and included in the Acknowledgements section)

The cover letter is a separate document uploaded through the submission portal. For Nature Methods, the cover letter should clearly state what the method does, what problem it solves, and why it's a significant advance over existing approaches. Editors use the cover letter for triage, so don't waste it on generic praise for the journal.

Nature Methods has several requirements and conventions that go beyond standard Nature Portfolio guidelines.

1. Reproducibility is the editorial priority. Nature Methods editors evaluate manuscripts primarily on whether the method can be reproduced by other labs. Vague methods descriptions are the single most common reason for revision requests. Include exact software versions, parameter settings, hardware specifications (for computational methods), and reagent catalog numbers (for experimental methods).

2. Method validation expectations are high. Showing that your method works on your own data isn't sufficient. Nature Methods expects validation on independent datasets, comparison against established methods using accepted benchmarks, and ideally, independent validation by a collaborating lab. If you can't get independent validation, be explicit about limitations.

3. The "Online Methods" section is where the real paper lives. For methods journals, the 3,000-word Online Methods section is often more important than the main text. Reviewers spend more time on it, and readers rely on it for implementation. Don't treat it as an afterthought. Write it with the same care as the main text.

4. Code review is real. Reviewers will download your code, try to install it, and attempt to run the examples. If your GitHub repository has a broken build, missing dependencies, or unclear documentation, expect a major revision request regardless of the science.

5. Nature Methods uses a two-stage review for some submissions. For Articles describing complex methods, the journal sometimes invites a "technical referee" in addition to the standard reviewers. This referee focuses exclusively on reproducibility and methodological rigor, not novelty or biological significance.

6. Benchmark datasets must be specified precisely. When comparing methods, state the exact dataset version, download date, preprocessing steps, and train/test splits. "We used the MNIST dataset" isn't sufficient. "We used the MNIST dataset (LeCun et al., http://yann.lecun.com/exdb/mnist/, downloaded 2025-06-15, 60,000 training / 10,000 test images, no preprocessing)" is what they expect.

Nature Methods submissions require careful attention to both scientific rigor and formatting precision. The emphasis on reproducibility means that even small omissions, like a missing software version or an unclear parameter description, can trigger major revisions.

Manusights' AI-powered manuscript review checks your formatting against Nature Methods' specific requirements, including display item counts, reference style, structural organization, and word limits. It catches the formatting issues that are easy to miss when you're focused on the science.
