- Third-Generation Sequencing: Technologies like SMRT and Nanopore allow longer reads, ideal for structural variant detection and complex genome assembly.
2.2 Genomics Data Analysis
- Quality Control & Preprocessing: Use tools like FASTQC, Trimmomatic, or Cutadapt to assess read quality and trim adapters.
- Alignment & Mapping: Align reads to reference genomes with BWA or Bowtie for SNP and indel identification.
- Variant Calling & Annotation: Identify mutations using GATK and interpret effects with ANNOVAR or VEP.
2.3 Bioinformatics and Programming
- Python & R for Bioinformatics: Essential for data manipulation, visualization, and statistical modeling.
- Command-Line Tools: Master Samtools, Bedtools, and Bcftools for efficient large-scale data handling.
- Workflow Automation: Use Snakemake or Nextflow to automate sequencing pipelines, ensuring reproducibility.
2.4 Data Interpretation & Visualization
- Gene Expression Analysis: Tools like DESeq2 and edgeR help identify differentially expressed genes in RNA-seq studies.
- Pathway Analysis: Databases such as KEGG and Reactome map genetic variations to functional pathways.
- Structural Variants & Copy Number Analysis: Detect large-scale rearrangements using CNVkit or Manta, vital in cancer genomics.
