# 1. Quality control of raw sequencing reads
fastqc. Fastq # 2. Align reads to a reference genome
hisat2 -x genome_index -U reads. Fastq -S aligned. Sam # 3. Convert SAM to BAM and sort
samtools view -bS aligned. Sam > aligned. Bam
samtools sort aligned. Bam -o aligned_sorted. Bam # 4. Count reads mapping to genes
featureCounts -a annotation. Gtf -o counts. Txt aligned_sorted. Bam # 5. Perform differential expression analysis in R
# (Simplified code snippet)
library(DESeq2)
dds <- DESeqDataSetFromMatrix(countData = counts_matrix, colData = sample_info, design = ~ condition)
dds <- DESeq(dds)
res <- results(dds)
