I'm lost at the NCBI FTP server. Which file contains all chromosomes of GRCh37.p13 in one fasta? The program that I want to use takes one fasta file as the reference sequence. At ftp://ftp.ncbi.nih.gov/genomes/Homo_sapiens/ARCHIVE/ I don't see GRCh37.p13 and I don't see a README file .. I'm a little bit stuck here.
