Choosing a Bioinformatics Preprint Server

By Dr. Zubair Khalid, DVM, MS, PhD · 2026-08-27

Quick Answer

• Post your bioinformatics work on a preprint server like bioRxiv to establish priority, invite community feedback, and accelerate your research visibility before journal publication.
• Select a server that matches your research area, prepare your manuscript with proper licensing and data availability statements, and share the preprint link across professional networks.
• Preprints do not replace peer review, and some journals have policies about prior preprint posting, so verify target journal policies before submission.

Understanding Preprint Servers in Bioinformatics

Preprint servers are online platforms where researchers can share complete, unpublished manuscripts before formal peer review and journal publication. In bioinformatics, these servers have become essential infrastructure for rapid dissemination of methods, software, and computational findings. The most prominent server in the life sciences is bioRxiv, which hosts thousands of preprints across multiple subject areas including bioinformatics, genomics, and computational biology.

The value of preprints in bioinformatics is particularly pronounced because the field moves quickly. Computational methods, software tools, and analytical pipelines become outdated rapidly, and researchers need timely access to new approaches. A preprint allows you to share your work immediately upon completion of the analysis, instead of waiting months or years for journal review and publication.

Preprint servers also provide a permanent record with a digital object identifier (DOI), which establishes the date of your discovery. This priority claim is important in competitive research areas where multiple groups may be working on similar problems. The timestamped preprint serves as evidence of when you made your findings public.

How Preprints Differ From Journal Publications

A preprint is a manuscript that has not undergone peer review. It may be identical to the version you submit to a journal, or it may be a preliminary version that you plan to revise. The preprint server performs basic screening for plagiarism and inappropriate content, but it does not evaluate the scientific merit of your work.

Journal publication involves peer review by experts in your field, editorial decisions, revisions, and ultimately acceptance or rejection. This process adds credibility and quality assurance, but it also adds time. The median time from submission to publication can be many months, and rejection often means starting the process over with another journal.

Preprints and journal publications are complementary. You can post a preprint when your manuscript is ready, then submit it to a journal. The journal version, once accepted, becomes the version of record. Many journals now allow prior preprint posting, and some actively encourage it. However, you must check each journal's policy because some journals still consider preprints to be prior publication.

The Role of Preprints in Career Development

For bioinformatics researchers, preprints serve as a career development tool. They demonstrate your research productivity to potential employers, collaborators, and funding agencies. A preprint shows that you have completed work and are willing to share it publicly, which signals confidence and openness.

Preprints also help you build a professional reputation. When you post a preprint, you can share the link on social media, professional networks, and mailing lists. This increases the visibility of your work and can lead to invitations to collaborate, speak at conferences, or apply for positions.

The National Institutes of Health Office of Intramural Training and Education emphasizes that professional development in research includes sharing your work and building your scientific identity. Preprints are one mechanism for this sharing. Similarly, the American Society for Microbiology career resources highlight the importance of networking and professional visibility for career advancement in the life sciences.

Selecting the Right Preprint Server

Major Preprint Servers for Bioinformatics

Several preprint servers serve the bioinformatics community. The most widely used is bioRxiv, which covers the entire life sciences field including bioinformatics. bioRxiv is operated by Cold Spring Harbor Laboratory and is free to use for both posting and reading. It assigns DOIs to all preprints and makes them searchable through Google Scholar and other databases.

medRxiv is a related server for medical and clinical research. If your bioinformatics work involves clinical applications, such as diagnostic tools or clinical genomics, medRxiv may be appropriate. However, medRxiv has additional screening requirements for medical research, including verification that the study has appropriate ethical approvals.

Other servers exist for specific fields. For example, arXiv has a quantitative biology section that hosts some bioinformatics work, particularly those with a strong mathematical or statistical focus. The choice of server depends on your research area and your target audience.

Matching Your Work to the Server

The choice of server should match the nature of your work. If your bioinformatics research is primarily biological, such as genome analysis, transcriptomics, or phylogenetics, bioRxiv is the appropriate choice. If your work is primarily mathematical or statistical, arXiv may be more suitable. If your work has direct clinical implications, medRxiv may be appropriate.

Consider where your target audience is likely to look. Researchers in your field will have preferred servers they check regularly. Posting to the server that your colleagues and potential collaborators use increases the chances that your work will be seen.

Server Policies and Screening

Each preprint server has its own policies and screening procedures. bioRxiv screens submissions for plagiarism, inappropriate content, and whether the manuscript is a preprint. The screening is not a scientific review. The server does not evaluate the quality of the research.

Before submitting, read the server's policies carefully. Some servers have restrictions on the types of research they accept. For example, bioRxiv does not accept clinical trials or case reports. If your bioinformatics work involves clinical data, you may need to use medRxiv instead.

Preparing Your Bioinformatics Preprint

Manuscript Structure and Content

A bioinformatics preprint should follow the same structure as a journal manuscript. Include a title, abstract, introduction, methods, results, discussion, and references. The methods section is particularly important in bioinformatics because the computational details determine whether others can reproduce your work.

Describe your data sources, software versions, parameters, and analysis pipelines in sufficient detail. If you used existing software, cite it and specify the version. If you developed new software, provide the source code and instructions for installation and use. The goal is to allow another researcher to reproduce your analysis from your description.

Data and Code Availability

Data and code availability is a critical component of a bioinformatics preprint. The manuscript should include a statement that describes where the data and code can be accessed. If the data are in a public repository, provide the accession numbers. If the code is on GitHub or another repository, provide the URL.

The NIH Office of Intramural Training and Education emphasizes that sharing data and code is part of responsible research conduct. Many journals now require data availability statements, and preprint servers encourage them. Making your data and code available increases the credibility of your work and allows others to build on it.

Software and Tools

If your bioinformatics work involves new software, include a section that describes the software, its features, and its availability. Provide the URL where the software can be downloaded and instructions for installation. If the software is open source, state the license under which it is distributed.

Consider providing a containerized version of your software, such as a Docker image, to make it easier for others to run. This is particularly helpful for complex pipelines with many dependencies. The container should include all the dependencies and the instructions for running the analysis.

Figures and Tables

Figures and tables should be clear and self-contained. Each figure should have a caption that explains what it shows and how it was generated. In bioinformatics, figures often show plots of data, diagrams of pipelines, or screenshots of software interfaces. Ensure that the figures are legible when viewed on a screen, since most readers will view the preprint online.

Tables should be formatted for easy reading. Include the tables in the manuscript or provide them as supplementary files. If the tables are large, such as lists of differentially expressed genes, provide them as supplementary files instead of in the main text.

Submitting Your Preprint

Step-by-Step Submission Process

The submission process for bioRxiv is straightforward. Create an account on the bioRxiv website, then follow the submission instructions. You will need to provide the manuscript file, the title, the abstract, and the author information. You will also need to select the subject category that best fits your work.

The screening process typically takes a few days. The server checks the manuscript for plagiarism and for content that is not appropriate for the server. If the manuscript passes screening, it is posted publicly and assigned a DOI. You will receive an email with the link to your preprint.

Timing Your Submission

Consider the timing of your submission carefully. If you are planning to submit the manuscript to a journal, you can post the preprint at the same time or before. Some researchers post the preprint first, then submit to a journal. Others submit to the journal and post the preprint simultaneously.

The timing may also depend on your career goals. If you are applying for jobs or fellowships, posting a preprint before the application deadline can strengthen your application. The preprint demonstrates your research productivity and your ability to complete and share work.

Licensing Your Preprint

Preprint servers allow you to choose a license for your work. The most common choice is a Creative Commons license, which specifies how others can use your work. The CC BY license allows others to distribute, remix, and build upon the work, even commercially, as long as they credit you. The CC BY-NC license adds a noncommercial restriction.

The choice of license affects how others can use your work. A more permissive license, such as CC BY, allows the widest use. A more restrictive license, such as CC BY-NC, limits commercial use. Consider your preferences and the norms in your field when choosing a license.

Using Your Preprint to Build Visibility

Sharing Your Preprint

Once your preprint is posted, share the link widely. Post it on social media platforms such as Twitter, LinkedIn, and ResearchGate. Send it to colleagues and collaborators. Include the link in your email signature and on your professional website.

The NIH Office of Intramural Training and Education emphasizes the importance of networking and sharing your work for career development. Sharing your preprint is a concrete way to build your professional network and increase the visibility of your research.

Engaging With Feedback

Preprints allow readers to comment on your work. Some servers have a comment feature, and readers may also contact you directly by email. Engage with the feedback you receive. Respond to comments, answer questions, and consider whether the feedback suggests improvements to your work.

Feedback on a preprint can improve the manuscript before journal submission. A reader may point out an error, suggest a better analysis, or provide a reference you missed. Incorporating this feedback can strengthen the journal version of your manuscript.

Tracking Your Preprint

Monitor the attention your preprint receives. Some servers provide metrics such as the number of downloads and the number of citations. You can also use tools such as Google Scholar to track citations. This information can be useful for your CV and for demonstrating the impact of your work.

Building a Professional Profile

A preprint is a component of your professional profile. It demonstrates your research skills and your ability to communicate your work. When you apply for jobs or fellowships, you can include the preprint in your application materials. The preprint provides evidence of your productivity and your commitment to open science.

The U.S. Bureau of Labor Statistics Occupational Outlook Handbook describes the work of biochemists and biophysicists, which includes bioinformatics researchers. The handbook notes that these professionals conduct research and share their findings. Preprints are a mechanism for sharing findings.

From Preprint to Journal Publication

Choosing a Journal

After posting a preprint, you can submit the manuscript to a journal. Choose a journal that fits the scope of your work and your target audience. Consider the journal's impact factor, its audience, and its policies on preprints.

Check the journal's policy on preprints before submitting. Most journals allow prior publication, but some do not. The journal's website will state its policy. If the journal does not allow preprints, you may need to remove the preprint or choose a different journal.

Revising the Manuscript

The journal submission process may require revisions to the manuscript. The peer review process will provide feedback from experts in the field. Address the feedback carefully and revise the manuscript accordingly. The revised manuscript may differ from the preprint.

When the journal version is accepted, it becomes the version of record. The preprint remains available, but the journal version is the one that is cited. Some journals allow you to update the preprint to link to the published version.

The Relationship Between Preprint and Journal

The preprint and the journal version are related but distinct. The preprint is the version that was posted before peer review. The journal version is the version that was accepted after peer review. The journal version may have been revised based on the feedback.

The preprint provides a record of the work at the time it was posted. The journal version provides the final, peer-reviewed version. Both are part of the research record. The preprint shows the work in progress, and the journal version shows the completed work.

Records and Measurements

Tracking Preprint Impact

Maintain records of your preprint activity. Record the date of submission, the date of posting, and the DOI. Track the number of views and downloads over time. This information is useful for your CV and for demonstrating the impact of your work.

The preprint server provides some metrics, such as the number of downloads and the number of citations. You can also use Google Scholar to track citations. Record these metrics at regular intervals, such as monthly, to track the growth of your preprint's impact.

Documenting Feedback

Keep a record of the feedback you receive on your preprint. This includes comments on the preprint platform, emails from readers, and discussions on social media. Document the feedback and your response to it. This record is useful when you revise the manuscript for journal submission.

The feedback may include suggestions for improvement, questions about the methods, or requests for additional data. Documenting the feedback helps you address it systematically. It also provides a record of the community engagement with your work.

Maintaining a Publication Log

Maintain a publication log that includes your preprints and your journal publications. The log should include the title, the date, the DOI, and the status of each work. This log is useful for your CV, for your annual reports, and for your job applications.

The publication log is a professional record of your research output. It demonstrates your productivity and your ability to complete and share work. It is a useful tool for career development.

Common Failure Patterns

Submitting to the Wrong Server

A common failure is submitting a manuscript to a server that does not fit the work. For example, submitting a clinical bioinformatics manuscript to bioRxiv may result in rejection because bioRxiv does not accept clinical trials. The manuscript may be screened out, and you will need to submit to a different server.

To avoid this, check the server's policies before submitting. Read the instructions carefully and ensure that your work fits the scope of the server. If you are unsure, contact the server's staff for guidance.

Incomplete Data and Code Availability

Another common failure is submitting a preprint without providing the data and code. This reduces the credibility of the work and makes it difficult for others to reproduce the results. The preprint should include a data availability statement and provide the data and code.

Ignoring Feedback

Some researchers post a preprint and then ignore the feedback. This is a missed opportunity. The feedback can improve the work and help you prepare for journal submission. Engage with the feedback and use it to improve the manuscript.

Not Checking Journal Policies

A failure is submitting a manuscript to a journal that does not allow preprints. This can cause problems with the journal submission. Check the journal's policy before submitting. If the journal does not allow preprints, you may need to remove the preprint or choose a different journal.
