ChIP-seq流程结果文件解读

作者:互联网

接前面文章:ChIP-seq | ATAC-seq | RNA-seq | 数据分析流程

前面已经把pipeline跑完了,但是关于结果的解读还是不清楚,这里来深入探讨一下。

 

复习:

 

输入文件:~/project/epigenetic/analysis/ChIP-seq/encode-pipeline/encc/H3K27ac/encc.chip.full.json

"chip.title" : "hENCC ChIP-seq (H3K27ac)",
"chip.description" : "ENCC-K27-2_1,ENCC-I1_1 (1st); ENCC-K27-1_1,ENCC-I2_1 (2st) ",

"chip.pipeline_type" : "histone",
"chip.aligner" : "bowtie2",
"chip.align_only" : false,
"chip.true_rep_only" : false,

"chip.genome_tsv" : "~/softwares/chip-seq-pipeline2/db/hg19.tsv",

"chip.paired_end" : true,
"chip.ctl_paired_end" : true,

"chip.fastqs_rep1_R1" : [ "~/project2/analysis/ChIP-seq/encode-pipeline/encc/fastq/ENCC-K27-2_1.fastq.gz" ],
"chip.fastqs_rep1_R2" : [ "~/project2/analysis/ChIP-seq/encode-pipeline/encc/fastq/ENCC-K27-2_2.fastq.gz" ],
"chip.fastqs_rep2_R1" : [ "~/project2/analysis/ChIP-seq/encode-pipeline/encc/fastq/ENCC-K27-1_1.fastq.gz" ],
"chip.fastqs_rep2_R2" : [ "~/project2/analysis/ChIP-seq/encode-pipeline/encc/fastq/ENCC-K27-1_2.fastq.gz" ],

"chip.ctl_fastqs_rep1_R1" : [ "~/project2/analysis/ChIP-seq/encode-pipeline/encc/fastq/ENCC-I1_1.fastq.gz" ],
"chip.ctl_fastqs_rep1_R2" : [ "~/project2/analysis/ChIP-seq/encode-pipeline/encc/fastq/ENCC-I1_2.fastq.gz" ],
"chip.ctl_fastqs_rep2_R1" : [ "~/project2/analysis/ChIP-seq/encode-pipeline/encc/fastq/ENCC-I2_1.fastq.gz" ],
"chip.ctl_fastqs_rep2_R2" : [ "~/project2/analysis/ChIP-seq/encode-pipeline/encc/fastq/ENCC-I2_2.fastq.gz" ],

  

输出文件:
