NANOG targets among first 50 MEM results. MEM query with transcription factor NANOG retrieves more of its targets among top 50 genes, than queries on any one dataset individually. Each point represents the overlap between NANOG targets and top 50 query results in one of the 487 datasets. The datasets are sorted by variation and the ones that pass standard deviation filter are highlighted. Most of the datasets that retrieve high number of NANOG targets pass the filter, which shows the specificity of the filter.
