This directory contains compressed multiple alignments of 7 virus sequences.
These 7 sequences represent coronavirus strains in human populations

The 'reference' sequence for this collection is the sequence:

  NC_045512v2 - 2019-12-30 - Wuhan-Hu-1
  https://www.ncbi.nlm.nih.gov/nuccore/NC_045512.2

Description files in this directory:

  md5sum.txt - md5 sums to verify copied files
  wuhCor1.7way.nameList.txt - relating the accession name to
                              sequence name, and sample collection date

  wuhCor1.7way.nh - Phylogenetic tree used for multiz alignment.
           The phylogenetic tree was calculated on 31mer frequency similarity
           and neighbor joining that distance matrix with the phylip toolset:
           http://evolution.genetics.washington.edu/phylip.html
           'neighbor' command:
           http://evolution.genetics.washington.edu/phylip/progs.data.dist.html

  wuhCor1.multiz7way.maf.gz - alignments with gap annotation with
                                accession identifiers

  dnaFasta7.fa.tgz - gzipped tar file for the DNA fasta, 7 sequences
                - to extract sequences: tar xvzf dnaFasta7.fa.tgz
                - creates seven files:

To download a large file or multiple files from this directory, we recommend
that you use rsync or ftp rather than downloading the files via our website.

Via rsync:
rsync -avz --progress \
        rsync://hgdownload.soe.ucsc.edu/goldenPath/wuhCor1/multiz7way/ ./

Via FTP:
    ftp hgdownload.soe.ucsc.edu
    user name: anonymous
    password: <your email address>
    go to the directory goldenPath/wuhCor1/multiz7way

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.
