Hi
I would highly appreciate if you could show me how to create a bed file around 
the TSSs from UCSC databases such as ensembl or refSeq genes. I need 350 
nucleotides upstream and 150 nucleotides downstream of TSSs. The bed file should 
look like below, where:
chromStart is 350 nucleotides upstream of TSS
chromEnd is 150 nucleotides downstream of TSS
name is Name of gene or transcript_id depending on the database.



chrom    chromStart    chromEnd    name        score    strand
chr1    67051159    67163158    NM_024763    0    -    
chr1    67075869    67163158    NM_207014    0    +    
chr1    16762998    16812569    NM_017940    0    -    

Thanks
Joseph
