###################################################################### README for annotation files Last updated: April 19, 2017 ###################################################################### The files in this directory are provided to provide a common path to the latest genome feature annotation and variation files available for the human GRCh37 and GRCh38 assemblies. The files provided are symlinks to files located elsewhere on NCBI's FTP site, as indicated in the README.txt file in each directory. Due to limitations of the particular file specifications, the files themselves may not indicate the specific details of the genome assembly or annotation date or release. Therefore, it is strongly recommended to download the corresponding README file and note the download date in order to be able to match the file contents to a particular archived dataset.
