Fig. 2

A A heatmap indicating the relative paucity or abundance of software in the range of possible accuracy and speed rankings. Redder colours indicate an abundance of software tools in an accuracy and speed category, while bluer colours indicate scarcity of software in an accuracy and speed category. The abundance is quantified using a Z-score computation for each bin, this is derived from 1000 random permutations of speed and accuracy ranks from each benchmark. Mean normalised ranks of accuracy and speed have been binned into 9 classes (a 3×3 grid) that range from comparatively slow and inaccurate to comparatively fast and accurate. Z-scores with a P value less than 0.05 are indicated with a ‘X’. B The z-score distributions from the permutation tests (indicated with the wheat coloured violin plots) compared to the z-score for the observed values for each of the corner and middle square of the heatmap
