What can I submit?

The short answer is anything regarding the reproducibility of a published paper. Naturally, this begs the question: what is reproducibility? It is hard to give a short answer to this question, for several definitions are available and they may change depending on the field. As we believe in the power of the scientific community, we do not want to restrict submissions based on a single definition. Instead, we shall try to walk you through some perspectives available that can guide your decision on whether some material is adequate to this website or not, finishing up with a summary and our view on this matter. Every definition we provide here are within our scope of valid submissions.

Reproducing or replicating?

Reproduction and replication of a study are often used as synonyms, but is there a difference between reproducing and replicating an analysis? We assume a broad range of types of research paper, so it could be a statistical analysis, a theoretical model, an experiment, a numerical algorithm, and so on. This broad spectrum of research becomes the main source of divergence in understanding. Some fields seem to use these words interchangeably with the same meaning, while other fields make a difference, which can be reversed between one field and another (Plesser, 2018). Here, we will assume that these two words do mean different things according to context, usually one meaning that the whole study setup is the same, and the other implying a different setup (e.g., samples, cohorts, environmental conditions, etc.).

The Turing Way Definition

The Turing Way is an open book (The Turing Way Community, 2019) that provides the following 4-fold definition, which one may use as personal guidance: reproducible, replicable, robust, generalizable. Each of these words is defined based on whether the repetition of the study in question employs the same analysis (or not) to the same dataset (or not). It leads to the following table.

Table 1: The Turing Way definition (The Turing Way Community, 2019)

In this definition, “same” has a quite strict assessment bar. For instance, given any analysis done in a computer, the same code and language must run on the same dataset for it to be a reproduction of the original study, while a code written by another person (possibly in another language) would lead to a robust result (or not), even if following the same algorithm but not the same code (e.g., depending on other libraries, component version, or written in a different language). Similarly, small changes in the analyzed data would already imply a replication, which virtually makes “reproduction” impossible in some fields, only replication may be achievable. Note that this is not a problem per se, since it is only a matter of naming definition.

An Expanded Definition

In SciGen.Report, all of the conditions listed in The Turing Way are valid targets to be evaluated and shared with the community. However, we aim for an even more ambitious range, including also partial analyses and partial data. By “partial” we mean slightly different things, that may fall in the following categories for data:

Regarding analyses, one must first suppose that a study may conduct a single analysis that cannot be broken into pieces, or a more complex or convoluted analysis that may be composed by smaller procedures. We may call the former atomic analysis, as it cannot be divided further. Any analysis that is not atomic may therefore be somehow split into partial analysis. By definition, atomic analysis cannot be partially conducted. For an analysis that is not atomic, we can conceive the following partial analysis pattern:

Note that data can be partially the same and partially different at the same time (say, half the same, and half different). Strictly speaking, in such cases, the difference “absorbs” the classification, leaving the data simply “partially different.” The same can be said about the analysis: if only some procedures are selected, and part of these are different, it is a partially different analysis. Hence, a revised version of The Turing Way definition can be summarized in Table 2.

In SciGen.Report, we want to address all this trials, no matter whether they are positive or negative results.
