Human Reactome has a 3 monthly release cycle. I will create the latest version possible for each Bioconductor release. Note: This latest version was built using mappings provided by Reactome. The previous versions had inconsistencies with the data on the website. I am aware that this version contains less mapped genes than the previous versions. I will look into the reasons and if required I will update the way I create the package and release a new version. Willem Ligtenberg willem@wligtenberg.nl
