Scientific Process

TNU Guidelines

The following flowchart summarises the scientific process at the TNU:


Analysis Plan

Prior to data analysis, an Analysis Plan is uploaded to and time-stamped on our internal repository (upon publication of the final paper, this analysis plan is copied to a public ETH repository). Whenever possible under the specific project’s constraints, studies are pre-registered at journals offering this service.



If possible, a "one-click" analysis pipeline running all analyses from the raw data to the results figures is created.

Before submitting a paper for publication (and before submitting a revision), the analysis pipeline is checked by a second person who has not been involved in data analysis. This process has the following two general aims:

1. Re-run the entire analysis pipeline on a different system and check that the results are reproducible.

2. Perform sanity checks of the code and verify that there are no obvious flaws in the analysis stream.

After code-review, any necessary corrections are implemented and checked again by the code reviewer before the paper can be finalised and submitted to the co-authors.

Final steps

The results and analysis pipeline are documented and stored in line with our TNU-internal Working Instructions.

The written paper is submitted to a preprint server before it is submitted to a peer-reviewed journal.

Data sharing is done by default but follows specific regulations as described in our “SOP Data Sharing” and first needs to be internally approved.
