'''PcTF vs. H3K27me3''' | |||
* Add Experiments to Import: added 1_aln_sorted.bam (PcTF), 2_aln_sorted.bam (PcTF mock), 6_aln_sorted.bam (H3K27me3), and 7_aln_sorted.bam (H3K27me3 mock) | |||
* Create binding proteins: created "PcTF" for 1_aln_sorted, and "H3K27me3" for 6_aln_sorted. | |||
* Set control 2_ and 7_aln_sorted as "yes" for "Is control?" | |||
* Set 2_aln_sorted as control for 1_aln_sorted. Set 7_aln_sorted as control for 6_aln_sorted. | |||
** <font color="red">This analysis required too much disk space</font> | |||
* Started over, but only used '''chromosomes 1-3''' as reference templates (trying a few at a time). | |||
** This worked | |||
Results/ Notes: | |||
* Peak Table: shows very few hits for PcTF, many more for H3K27me3, no overlap! | |||
* Display wig file on UCSC Genome browser online - add file from "ChIPseq Wig Files" folder as a custom track; wig file shows raw data histogram | |||
** 1_aln_sorted.wig, 6_aln_sorted.wig | |||
* Display BED file on UCSC Genome browser online - add file from "ChIPseq BED Files" folder as a custom track; BED file shows | |||
** 1_aln_sorted.bed, 6_aln_sorted.bed | |||
