Files included in this directory:
  - knownGene.exon*.fa.gz: for each exon in the hg18 UCSC Gene track, this
    file contains either amino acids (AA) or nucleotides (Nuc) for hg18 and the
    aligning genomes.
  - knownCanonical.exon*.fa.gz: for each exon in the hg18 canonical set of UCSC 
    Genes, this file contains either amino acids (AA) or nucleotides (Nuc) 
    for hg18 and the aligning genomes.
  - refGene.exon*.fa.gz: for each exon in the hg18 RefSeq Gene track, this file 
    contains either amino acids (AA) or nucleotides (Nuc) for hg18 and the 
    aligning genomes.

To download a large file or multiple files from this directory, we recommend 
that you use ftp rather than downloading the files via our website. To do so: 
    ftp hgdownload.cse.ucsc.edu 
    user name: anonymous
    password: <your email address>
    go to the directory goldenPath/hg18/multiz28way/alignments

To download multiple files from the UNIX command line, use the "mget" command. 
    mget <filename1> <filename2> ...
    - or -
    mget -a (to download all the files in the directory) 
Use the "prompt" command to toggle the interactive mode if you do not want 
to be prompted for each file that you download.
