Hi again Chittybabu,
I would like to add that you can start by uploading your BED file as a 
custom track.  Then, in Genome Graphs, you can hit the "import" button 
and select your custom track table to import.  Once that is done, your 
data will be available for graphing on the main Genome Graphs page.
I hope this helps get you started.  Please feel free to email 
gen...@soe.ucsc.edu again if you have further questions.
