核心说明

  • Complete workflow ,面向 raw ChIP-seq FASTQ files to annotated peaks。
  • 用于 sample in IP_rep1 IP_rep2 Input_rep1 Input_rep2;do fastp -i ${sample}_R1.fastq.gz -I ${sample}_R2.fastq.gz \ -o trimmed/${sample}_R1.fq.gz -O trimmed/${sample}_R2.fq.gz \ --detect_adapter_for_pe \ --qualified_quality_phred 20 \ --length_required 25 \ --html qc/${sample}_fastp.html done。

Align

for sample in IP_rep1 IP_rep2 Input_rep1 Input_rep2; do bowtie2 -p 8 -x bt2_index/genome
-1 trimmed/${sample}_R1.fq.gz
-2 trimmed/${sample}_R2.fq.gz

samtools sort -@ 4 -o aligned/${sample}.bam done


**QC Checkpoint:** Check alignment rate
- Overall alignment >80%
- Unique mapping >70%

## Narrow peaks (TFs, sharp histone marks like H3K4me3)

适用场景

  • Use bio-workflows-chipseq-pipeline ,用于 genomics 、 bioinformatics workflows。
  • Apply bio-workflows-chipseq-pipeline to sequencing,variant,或 omics analysis tasks。

不适用场景

  • Do not rely on this catalog entry alone ,用于 installation 或 maintenance details。
