DEAR EDITOR,rnSince the first reported severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)infection in December 2019,coronavirus disease 2019(COVID-19)has become a global pandemic,spreading to more than 200 countries and regions worldwide.With continued research progress and virus detection,SARS-CoV-2 genomes and sequencing data have been reported and accumulated at an unprecedented rate.To meet the need for fast analysis of these genome sequences,the National Genomics Data Center(NGDC)of the China National Center for Bioinformation(CNCB)has established an online coronavirus analysis platform,which includes de novo assembly,BLAST alignment,genome annotation,variant identification,and variant annotation modules.The online analysis platform can be freely accessed at the 2019 Novel Coronavirus Resource(2019nCoVR)(https://bigd.big.ac.cn/ncov/online/tools).
