Good Morning Sina:

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: Variation and Repeats, table: rmsk and then "describe table schema"

Note the definition of genoName, genoStart, genoEnd:

genoName        chr1    varchar(255)    Genomic sequence name
genoStart       10000   int(10) unsigned        Start in genomic sequence
genoEnd         10468   int(10) unsigned        End in genomic sequence

You can select these from the genome browser with the MySQL command:

mysql --user=genome --host=genome-mysql.cse.ucsc.edu -A -e "select 
genoName,genoStart,genoEnd from rmsk;" hg19

--Hiram
