First of all, thanks to Rafa for scooping me with my own article. Not sure if that’s reverse scooping or recursive scooping or…. The latest issue of _Science_ has a special section on Data Replication and Reproducibility. As part of the section I wrote a brief commentary on the need for reproducible research in computational science. _Science_ has a pretty tight word limit for it’s commentaries and so it was unfortunately necessary to omit a number of relevant topics.
