Stickleback 8-way conservation track, phastCons 8-Way raw data scores

These files are formatted as fixedStep wiggle files.
See also: http://genome.ucsc.edu/goldenPath/help/wiggle.html

A data section is introduced in each file with a line
declaring the chromosome, the starting position, and the span.
For example, chrM.data.gz begins:

fixedStep chrom=chrM start=1 step=1
0.927
0.944
0.967
... etc ...

Data values follow the fixedStep line. 
They start at the position specified by the 'start=N'
value on the fixedStep line.  In this example, the
first value 0.927 is at the first nucleotide of chrM,
the next value 0.944 is at the second nucleotide of chrM.
The 'step=1' specifies that each value spans a single
nucleotide.

There can be numerous fixedStep declarations in each file.
For nucleotide positions not covered by the data specified,
there are no data values.

NOTE: These raw data values are compressed into single-byte 
representations when loaded into the database for the Genome Browser 
display.  This compression results in some loss of precision.  This is
an acceptable trade-off because the data is further compressed for
the simple bar graph display in the Genome Browser. Because of this
compression, the values obtained from the database via the Table
Browser will differ from these raw data values.
