Software?

Research software is any software that is used to generate, process or analyse results that you intend to appear in a publication.

 

It can be anything from a few lines of code written by yourself, to a professionally developed software package.

What about Excel?

Is software important to research?

Growth in a Time of Debt

"All I can hope is that future historians note that one of the core empirical points providing the intellectual foundation for the global move to austerity in the early 2010s was based on someone accidentally not updating a row formula in Excel”

Mike Konczal, Roosevelt Institute

[4]

Ancient Ethiopian genome reveals extensive Eurasian admixture throughout the African continent

the geographic extent of the genetic impact of this migration was overestimated... the Yoruba and Mbuti do not show higher levels of Western Eurasian ancestry

[5]

The error is in the code that converts a 64-bit floating-point number to a 16-bit signed integer... the 64-bit numbers [are] larger... than [the previous code], triggering an overflow condition...

 

...[the] backup computer crashes, followed 0.05 seconds later by a crash of the primary computer.

What does the future hold?

Reproducibility

These slides: bit.ly/NBICNov19

The ability to reproduce an experiment and/or analysis and generate the same result as previously found

How can research be reproducible if a key contribution is hidden?

...it takes skill

Who writes the software?

Software sustainability

The software you use today is available for use in the future

  • Software engineering

  • Citation

  • Licensing

  • Community building

  • Training

  • Access to specialist skills

  • Funding

[7]

  • Software is vital to research

  • If you care about reproducibility, you must care about software

  • Ensuring that your software is available in the future is the goal of software sustainability
