DNA in a chromose

[GenoMax]

NCBI provides the annotation in separate files in the GFF format here: ftp://ftp.ncbi.nlm.nih.gov/genomes/H_sapiens/GFF/

Thanks, but I can't find the annotation files on NCBI which I downloaded form the link below:

http://www.ncbi.nlm.nih.gov/projects/genome/assembly/grc/human/

Does NCBI contain these annotation files?

The FASTA files with the genomic sequence do not label what portions of the sequence are coding. There are other annotation files that have that information (such as the refFlat.txt or refGene.txt from UCSC GB). As far as double-stranded DNA, the FASTA files only give the one strand, but the reverse complement is easy to determine for any sequence.

Hi,

I am using the GRCh37 assembly on NCBI website. My question is:
which parts of each chromosome in chr*.fa file is for DNA and RNA? and How I can find double stranded dna in this file.

Thanks
