Table 1.

Martini performance

Total input	Keyword enhancement time
100 abstracts	3 s
100 genes	2 min

This table can be used to estimate the time required for a Martini analysis, assuming linear scaling with total input size. For example, to perform a keyword enhancement using two sets of 500 genes (=total input of 1000 genes) takes ∼20 min, i.e. 10 times longer than for 100 genes. The estimates given here are for genes with nine Medline abstracts (i.e. the median number for human genes). Scaling can be highly non-linear, e.g. including well-studied genes can take much longer. However, in practice the actual time taken is often less than the time estimated from this table.
