This directory contains fasta files 
for human genomic sequence in the ENCODE regions, for 
the March 2006 (UCSC hg18, NCBI Build 36) build of the human genome.
The sequences are in the files:

    hg18.fa.gz          unmasked sequence (all upper case)
    hg18.msk.fa.gz      soft-masked sequence (repeats in lower case)

In July 2007, the ENCODE project transitioned from
the previous reference build (Build 35) to this one.
