5 # Introduction
|
jpayne@0
|
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.

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
|
jpayne@0
|
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)

34 # Output
|
jpayne@0
|
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.
