Added genomeRNAi filters and attributes for Human and Fruitfly. An example identifier has been added for all the RNAseq attributes. Ensembl Variation 70: Updated the human somatic variation database to COSMIC 61 data. Updated Mouse and Cow to dbSNP 137. "Minor allele frequency" and "Minor allele count" have been renamed to "1000 genomes global MAF" and "1000 genomes global MAC". Variation datasets have been renamed to "short variation (SNPs and indels)". Variation sources and Variation synonyms have been updated and reorganised in the filter and attribute sections. Ensembl Regulation 70: Added Binding motifs for Human and Mouse. New Ensembl Regulatory Features IDs list limit filter in the "Regulatory features" section, Vega 50 : Updated Human assembly to GRCh37.p10 and Mouse assembly to GRCm38.p1 A complete list of the changes in release 70 can be found at http://www.ensembl.org/info/website/news.html Best Regards, Thomas -- Thomas Maurel Bioinformatician - Ensembl Production Team European Bioinformatics Institute (EMBL-EBI) Wellcome Trust Genome Campus, Hinxton Cambridge - CB10 1SD - UK [[alternative HTML version deleted]]
