1 # SeqSero2 alpha-test version
2 Salmonella serotyping from genome sequencing data
3
4
5 # Introduction
6 SeqSero2 is a pipeline for Salmonella serotype determination from raw sequencing reads or genome assemblies. This is a alpha test version. For now, it can only accept separated paired-end reads. A web app will be available soon.
7
8 # Dependencies
9 SeqSero depends on:
10
11 1. Python 2.7 and [Biopython 1.65](http://biopython.org/wiki/Download);
12
13 2. [Burrows-Wheeler Aligner](http://sourceforge.net/projects/bio-bwa/files/);
14
15 3. [Samtools](http://sourceforge.net/projects/samtools/files/samtools/);
16
17 4. [NCBI BLAST](https://blast.ncbi.nlm.nih.gov/Blast.cgi?PAGE_TYPE=BlastDocs&DOC_TYPE=Download);
18
19 5. [SRA Toolkit](http://www.ncbi.nlm.nih.gov/Traces/sra/sra.cgi?cmd=show&f=software&m=software&s=software);
20
21 6. [SPAdes](http://bioinf.spbau.ru/spades);
22
23 7. [Bedtools](http://bedtools.readthedocs.io/en/latest/).

25 # Executing the code
26 Usage: SeqSero2.py
27
28 -p <int> (number of threads, if p >4, only 4 threads will be used for assembly since the amount of extracted reads is small, default=1)
29
30 -i <file> (/path/to/input/file; for now, SeqSero2 only accepts separated paired-end reads )
31
32 -b <string> (algorithms for bwa mapping; 'mem' for mem, 'sam' for samse/sampe; default=mem; optional; for now SeqSero2 is only optimized for "mem" mode)
33
34 # Output
35 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.
