Hi Hyunsoo, Unfortunately, UCSC Genes transcripts do not have polyA annotations. Instead use the Table Browser to do an intersection of UCSC Genes and the Poly(A) track. To do this, select Genes and Gene prediction tracks from the Group pull-down menu and then UCSC Genes from the track pull-down menu. Click the intersect button, and then choose mRNA and EST tracks from the Group pull-down menu and then Poly(A) from the track pull-down menu. Finally, choose the radio button "All UCSC Genes records that have no overlap with Poly(A)" and click submit.
I hope this information is helpful. Please feel free to contact the mail list again if you require further assistance.
