This is a alpha test version. A web app will be available soon. + + +# Dependencies +SeqSero has two modes: + + +(A) k-mer based mode (default), which applies unique k-mers of serotype determinant alleles to determine Salmonella serotypes in a fast speed. Special thanks to Dr. Hendrik Den Bakker for his significant contribution to this mode, details can be found in [SeqSeroK](https://github.com/hcdenbakker/SeqSeroK) and [SalmID](https://github.com/hcdenbakker/SalmID). + +K-mer mode is a independant pipeline, it only requires: + +1. Python 3; +2. [SRA Toolkit](http://www.ncbi.nlm.nih.gov/Traces/sra/sra.cgi?cmd=show&f=software&m=software&s=software) (optional, just used to fastq-dump sra files); + + +(B) allele based mode (if users want to extract serotype determinant alleles), which applies a hybrid approach of reads-mapping and micro-assembly. + +Allele mode depends on: + +1. Python 3; + +2. [Burrows-Wheeler Aligner](http://sourceforge.net/projects/bio-bwa/files/); + +3. [Samtools](http://sourceforge.net/projects/samtools/files/samtools/); + +4. [NCBI BLAST](https://blast.ncbi.nlm.nih.gov/Blast.cgi?PAGE_TYPE=BlastDocs&DOC_TYPE=Download); + +5. [SRA Toolkit](http://www.ncbi.nlm.nih.gov/Traces/sra/sra.cgi?cmd=show&f=software&m=software&s=software); + +6. [SPAdes](http://bioinf.spbau.ru/spades); + +7.

[SalmID](https://github.com/hcdenbakker/SalmID). + + +# Executing the code +Make sure all SeqSero2 and its dependency executables are added to your path (e.g. to ~/.bashrc). Then type SeqSero2_package.py to get detailed instructions. + + Usage: SeqSero2_package.py + + -m <string> (which mode to apply, 'k'(kmer mode), 'a'(allele mode), default=k) + + -t <string> (input data type, '1' for interleaved paired-end reads, '2' for separated paired-end reads, '3' for single reads, '4' for genome assembly, '5' for nanopore fasta, '6'for nanopore fastq) + + -i <file> (/path/to/input/file) + + -p <int> (number of threads for allele mode, if p >4, only 4 threads will be used for assembly since the amount of extracted reads is small, default=1) + + -b <string> (algorithms for bwa mapping for allele mode; 'mem' for mem, 'sam' for samse/sampe; default=mem; optional; for now we only optimized for default "mem" mode) + + -d <string> (output directory name, if not set, the output directory would be 'SeqSero_result_'+time stamp+one random number) + + -c <flag> (if '-c' was flagged, SeqSero2 will use clean mode and only output serotyping prediction without the directory containing log files) + + +# Examples +K-mer mode: + + # K-mer (default), for separated paired-end raw reads ("-t 2") + SeqSero2_package.py -t 2 -i R1.fastq.gz R2.fastq.gz + + # K-mer (default), for assemblies ("-t 4", assembly only predcited by K-mer mode) + SeqSero2_package.py -t 4 -i assembly.fasta + +Allele mode: + + # Allele mode ("-m a"), for separated paired-end raw reads ("-t 2"), use 10 threads in mapping and assembly ("-p 10") + SeqSero2_package.py -m a -p 10 -t 2 -i R1.fastq.gz R2.fastq.gz + + +# Output +Upon executing the command, a directory named 'SeqSero_result_Time_your_run' will be created. Your result will be stored in 'Seqsero_result.txt' in that directory. And the assembled alleles can also be found in the directory if using "-m a" (allele mode). + + +# Citation +Zhang S, Yin Y, Jones MB, Zhang Z, Deatherage Kaiser BL, Dinsmore BA, Fitzgerald C, Fields PI, Deng X. +Salmonella serotype determination utilizing high-throughput genome sequencing data. +**J Clin Microbiol.** 2015 May;53(5):1685-92.[PMID:25762776](http://jcm.asm.org/content/early/2015/03/05/JCM.00323-15)
