PGCGAP is a pipeline for prokaryotic comparative genomics analysis. It can take the pair-end reads, Oxford reads or PacBio reads as input. In addition to genome assembly, gene prediction and annotation, it can also get common comparative genomics analysis results such as phylogenetic trees of single-core proteins and core SNPs, pan-genome, whole-genome Average Nucleotide Identity (ANI), orthogroups and orthologs, COG annotations, substitutions (SNPs) and insertions/deletions (indels), and antimicrobial and virulence genes mining with only one line of commands.
The software was tested successfully on Windows WSL, Linux x64 platform, and macOS. Because this software relies on a large number of other software, so it is recommended to install with Bioconda.
Step1: Install PGCGAP
$conda create -n pgcgap python=3 $conda activate pgcgap $conda install pgcgap (Users in China can input "conda install -c https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/bioconda pgcgap" for instead)
Step2: Setup COG database (Users should execute this after the first installation of pgcgap)
$conda activate pgcgap $pgcgap --setup-COGdb $conda deactivate
Users with docker container installed have another choice to install PGCGAP.
$docker pull quay.io/biocontainers/pgcgap:
(see pgcgap/tags for valid values for <tag>)

Setup COG database
Check the required external programs (It is strongly recommended that this step be performed after the installation of PGCGAP):
$pgcgap --check-external-programs
Example 1: Perform all functions, take the Escherichia coli as an example, total 6 strains for analysis.
Notice: For the sake of flexibility, The "VAR" function needs to be added additionally.
$pgcgap --All --platform illumina --filter_length 200 --ReadsPath Reads/Illumina --reads1 _1.fastq.gz --reads2 _2.fastq.gz --suffix_len 11 --kmmer 81 --genus Escherichia --species “Escherichia coli” --codon 11 --strain_num 6 --threads 4 --VAR --refgbk /mnt/h/PGCGAP_Examples/Reads/MG1655.gbff --qualtype sanger
Example 2: Genome assembly.
Illumina reads assembly
In this dataset, the naming format of the genome is “strain_1.fastq.gz” and “strain_2.fastq.gz”. The string after the strain name is “_1.fastq.gz”, and its length is 11, so "--suffix_len" was set to 11.
$pgcgap --Assemble --platform illumina --assembler abyss --filter_length 200 --ReadsPath Reads/Illumina --reads1 _1.fastq.gz --reads2 _2.fastq.gz --kmmer 81 --threads 4 --suffix_len 11 $pgcgap --Assemble --platform illumina --assembler spades --filter_length 200 --ReadsPath Reads/Illumina --reads1 _1.fastq.gz --reads2 _2.fastq.gz --threads 4 --suffix_len 11 $pgcgap --Assemble --platform illumina --assembler auto --filter_length 200 --ReadsPath Reads/Illumina --reads1 _1.fastq.gz --reads2 _2.fastq.gz --kmmer 81 --threads 4 --suffix_len 11
Oxford reads assembly
Oxford nanopore only produces one reads file, so only the parameter of "--reads1" needs to be set, where the value is ".fasta". “--genomeSize” is the estimated genome size, and users can check the genome size of similar strains in the NCBI database for reference. The parameter was set to "4.8m" here. The suffix of the reads file here is ".fasta" and its length is 6, so "--suffix_len" was set to 6.
$pgcgap --Assemble --platform oxford --filter_length 200 --ReadsPath Reads/Oxford --reads1 .fasta --genomeSize 4.8m --threads 4 --suffix_len 6
PacBio reads assembly
PacBio also produces only one reads file "pacbio.fastq", the parameter settings are similar to Oxford. The strain name is "pacbio" with the suffix ".fastq" and the suffix length is 6, so "--suffix_len" was set to 6.
$pgcgap --Assemble --platform pacbio --filter_length 200 --ReadsPath Reads/PacBio --reads1 .fastq --genomeSize 4.8m --threads 4 --suffix_len 6
Hybrid assembly of short reads and long reads
Paired-end short reads and long reads in the directory “Reads/Hybrid/” were used as inputs. Illumina reads and long reads must be from the same isolates.
$pgcgap --Assemble --platform hybrid --ReadsPath Reads/Hybrid --short1 short_reads_1.fastq.gz --short2 short_reads_2.fastq.gz --long long_reads_high_depth.fastq.gz --threads 4

If the “--Annotate” function was run first, the files will be generated automatically.
