  2. Call variant calling using snippy

    ln -s ~/Tools/bacto/db/ .;
ln -s ~/Tools/bacto/envs/ .;
ln -s ~/Tools/bacto/local/ .;
cp ~/Tools/bacto/Snakefile .;
cp ~/Tools/bacto/bacto-0.1.json .;
cp ~/Tools/bacto/cluster.json .;

#download CU459141.gb from GenBank

    "recombination": false, (due to gubbins-error set false)
        "genus": "Varicella-zoster virus",
        "kingdom": "Viruses",
        "species": "Varicella-zoster virus"(in both prokka and mykrobe)
    "reference": "db/NC_001348.gb"
conda activate bengal3_ac3
(bengal3_ac3) /home/jhuang/miniconda3/envs/snakemake_4_3_1/bin/snakemake --printshellcmds

  3. Summarize all SNPs and Indels from the snippy result directory.

    #Output: snippy/summary_snps_indels.csv
# IMPORTANT_ADAPT the array isolates = ["AYE-S", "AYE-Q", "AYE-WT on Tig4", "AYE-craA on Tig4", "AYE-craA-1 on Cm200", "AYE-craA-2 on Cm200"]
python3 ~/Scripts/summarize_snippy_res.py snippy
cd snippy
grep -v "None,,,,,,None,None" summary_snps_indels.csv > summary_snps_indels_.csv

  4. Using spandx calling variants (almost the same results to the one from viral-ngs!)

    mamba activate /home/jhuang/miniconda3/envs/spandx
mkdir ~/miniconda3/envs/spandx/share/snpeff-5.1-2/data/NC_001348
cp NC_001348.gb  ~/miniconda3/envs/spandx/share/snpeff-5.1-2/data/NC_001348/genes.gbk
vim ~/miniconda3/envs/spandx/share/snpeff-5.1-2/snpEff.config
/home/jhuang/miniconda3/envs/spandx/bin/snpEff build NC_001348    #-d
~/Scripts/genbank2fasta.py NC_001348.gb
mv NC_001348.gb_converted.fna NC_001348.fasta    #rename "NC_001348.1 xxxxx" to "NC_001348" in the fasta-file
ln -s /home/jhuang/Tools/spandx/ spandx
(spandx) nextflow run spandx/main.nf --fastq "trimmed/*_P_{1,2}.fastq" --ref NC_001348.fasta --annotation --database NC_001348 -resume

# Rerun SNP_matrix.sh due to the error ERROR_CHROMOSOME_NOT_FOUND in the variants annotation
cd Outputs/Master_vcf
(spandx) cp -r ../../snippy/VZV_20S/reference .
(spandx) cp ../../spandx/bin/SNP_matrix.sh ./
#Note that ${variant_genome_path}=NC_001348 in the following command, but it was not used after command replacement.
#Adapt "snpEff eff -no-downstream -no-intergenic -ud 100 -formatEff -v ${variant_genome_path} out.vcf > out.annotated.vcf" to
"/home/jhuang/miniconda3/envs/bengal3_ac3/bin/snpEff eff -no-downstream -no-intergenic -ud 100 -formatEff -c reference/snpeff.config -dataDir . ref out.vcf > out.annotated.vcf" in SNP_matrix.sh
(spandx) bash SNP_matrix.sh NC_001348 .

  5. Calling inter-host variants by merging the results from snippy+spandx (Manually!)

    # Inter-host variants（宿主间变异）:一种病毒在两个人之间有不同的基因变异，这些变异可能与宿主的免疫反应、疾病表现或病毒传播的方式相关。
cp All_SNPs_indels_annotated.txt All_SNPs_indels_annotated_backup.txt
vim All_SNPs_indels_annotated.txt

  6. Calling intra-host variants using viral-ngs (http://xgenes.com/article/article-content/347/variant-calling-for-herpes-simplex-virus-1-from-patient-sample-using-capture-probe-sequencing/)

    # Intra-host variants（宿主内变异）：同一个人感染了某种病毒，但在其体内的不同细胞或器官中可能存在多个不同的病毒变异株。
mamba activate /home/jhuang/miniconda3/envs/viral-ngs4

  1. Using the bowtie of vrap to map the reads on ref_genome/reference.fasta (The reference refers to the closest related genome found from the list generated by vrap)

cd bowtie
mv mapped mapped.sam
samtools view -S -b mapped.sam > mapped.bam
samtools sort mapped.bam -o mapped_sorted.bam
samtools index mapped_sorted.bam
samtools view -H mapped_sorted.bam
