Reproducibility Check: CODECHECK

Would you like to certify the reproducibility of your research outputs? Do you care about increasing the trustworthiness of the science you deliver? Read the information below about the UT CODECHECK service.

Introduction

To improve the reproducibility of scientific publications by researchers at the University of Twente, the UT DCC collaborates with 4TU.ResearchData, TU Delft DCC, OSC-Twente, and the CodeCheck project to offer Reproducibility Checks.

A Reproducibility Check is a light-touch, independent peer review that checks whether your code and data can generate the computational results presented in your scientific publication. It does not evaluate the scientific validity of your findings or provide a code review - its sole purpose is to check that your results can be reproduced.

What to expect

During a Reproducibility Check, a member of our team will execute the code and workflows associated with your research article to verify if some or all of the successful results can be reproduced (e.g. tables, figures, etc.). If we can replicate your findings, your publication will receive a certificate of reproducible computation confirming that your research outputs can be reproduced independently. The certificate will be published in Zenodo and in the CodeCheck register. You can include the certificate in your code repository or share it with journals when submitting to demonstrate that your results are reproducible. Your code added code repository will receive a code works badge signaling that it meets reproducibility standards.

How to apply

This service is currently available to UT researchers who have deposited (or will deposit) the code and data associated with their scientific publication in the 4TU.ResearchData repository. We encourage UT PhD candidates and researchers who have developed code for research purposes to apply. All UTwente researchers are eligible to use this repository to publish their research outputs. If your publication’s code and data are deposited there, you can request a Reproducibility Check via software-stewards-lisa@utwente.nl.

Before submitting your request, please ensure you have the following:

A published paper or publicly available preprint
Code and associated data with the publication, archived in the 4TU.ResearchData repository
Clear, step-by-step instructions on how to execute your code to replicate the results in your publication (Preferably as documentation associated with the archived artifacts)

CODECHECK calls

The calls aim to boost CODECHECK contributions at UT and create a space for self-minded researchers who engage in Open Science and computational reproducibility. CODECHECK calls will be held every year. Subscribe to the monthly OSCT newsletter so that you don't miss any CODECHECK calls.
