Good Morning Joshua:

Please note, you can view the table schema for any table in the genome
browser via the "tables" link in the blue navigation bar.  Select
group: "Regulation", track "CpG Islands" and then "describe table schema"

bin     585     smallint(6)     range   Indexing field to speed chromosome 
range queries.
chrom   chr1    varchar(255)    values  Reference sequence chromosome or 
scaffold
chromStart      28735   int(10) unsigned        range   Start position in 
chromosome
chromEnd        29810   int(10) unsigned        range   End position in 
chromosome
name    CpG: 116        varchar(255)    values  CpG Island
length  1075    int(10) unsigned        range   Island Length
cpgNum  116     int(10) unsigned        range   Number of CpGs in island
gcNum   787     int(10) unsigned        range   Number of C and G in island
perCpg  21.6    float   range   Percentage of island that is CpG
perGc   73.2    float   range   Percentage of island that is C or G
obsExp  0.83    float   range   Ratio of observed(cpgNum) to 
expected(numC*numG/length) CpG in island

You can select specific rows directly from the public MySQL server:

mysql --user=genome --host=genome-mysql.cse.ucsc.edu -A -e "select 
chrom,chromStart,chromEnd,name from cpgIslandExt;" hg19

--Hiram
