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.
The NCBI record for GRCh37.p13 (GCF_000001405.25) can be found here: <a href="https://www.ncbi.nlm.nih.gov/search/?expt_dict=b&term=grch37.p13">https://www.ncbi.nlm.nih.gov/search/?expt_dict=b&term=grch37.p13</a>.

Click on *Download* and then select *Genomic FASTA* and *RefSeq*:

The tar file contains the complete NCBI version of the genome release in FASTA format.
