==Target selection for NimbleGen SeqCap EPI Choice== *Dinh's UMRs cover over 40Mb. In order to fit in the 30Mb limit of NimbleGen's array, I first removed all repetitive regions from the UMRs. /home/kunzhang/softwares/bedtools-2.17.0/bin/bedtools subtract -a blood.UMRs.tab.txt -b hg19_rmsk_bed.txt > blood.UMRs.non-repetitive.bed *Then I merge with the LMS clusters cat blood.UMRs.non-repetitive.bed whole_blood_LMS_clusters_BED.txt | sort -k 1,1 -k 2,2n | /home/kunzhang/softwares/bedtools-2.17.0/bin/bedtools merge -d 80 -i - > blood.UMRs.non-repetitive.blood_LMS_clusters.merged.bed.txt *To further reduce the total capture size, I extracted 29,936 regions that are autosomal and 100-2750bp. The total size is 28.4Mb. *For the regions larger than 2.75kb, I did the interection with the blood LMS clusters, and included the 3146 regions to the target list. /home/kunzhang/softwares/bedtools-2.17.0/bin/bedtools intersect -a blood.UMRs.non-repetitive.blood_LMS_clusters_2.75kUp.merged.bed -b whole_blood_LMS_clusters_BED.txt > blood.UMRs.non-repetitive.blood_LMS_clusters_2.75kUp.merged.whole_blood_LMS_clusters.bed.txt *The final list has 33,082 targets and a total size of 29.4Mb: [[Media:UCSD_Zhang_UMR_27Aug2014.bed.txt|UCSD_Zhang_UMR_27Aug2014.bed]]
