Installation
Dependencies
The simplest way to install dependencies is to use the Brew (MacOS) or Linuxbrew (Linux) packaging system.
$ brew tap brewsci/bio
$ brew install ispcr blast mlst
Installing
The easiest way of installing meningotype
is using pip
:
$ pip install --user git+https://github.com/MDU-PHL/meningotype.git
The --user
option will install the package locally, rather than in the global python
directory.
Thus, by default, this will install the package in $HOME/.local/
, and the executable in $HOME/.local/bin/
.
To install the executable in a custom location (e.g., $HOME/bin
), use the following:
$ pip install --install-option="--install-scripts=$HOME/bin" --user git+https://github.com/MDU-PHL/meningotype.git
To upgrade to a newer version:
$ pip install --upgrade --install-option="--install-scripts=$HOME/bin" --user git+https://github.com/MDU-PHL/meningotype.git
Testing
Once installed, you can run the following to ensure meningotype
is successfully working:
$ meningotype.py --test
If everything works, you will see the following:
$ meningotype.py --test
Running meningotype.py on test examples ...
$ meningotype.py A.fna B.fna C.fna W.fna X.fna Y.fna

$ meningotype.py -h
usage:

In silico typing for Neisseria meningitidis
Default: Serotyping, MLST and ctrA PCR
PCR Serotyping Ref: Mothershed et al, J Clin Microbiol 2004; 42(1): 320-328
PorA and FetA typing Ref: Jolley et al, FEMS Microbiol Rev 2007; 31: 89-96
Bexsero antigen sequence typing (BAST) Ref: Brehony et al, Vaccine 2016; 34(39): 4690-4697

positional arguments:
FASTA input FASTA files eg. fasta1, fasta2, fasta3 ... fastaN
optional arguments:
-h, --help show this help message and exit
--finetype perform porA and fetA fine typing (default=off)
--porB perform porB sequence typing (NEIS2020) (default=off)
--bast perform Bexsero antigen sequence typing (BAST) (default=off)
--mlst perform MLST (default=off)
--all perform MLST, porA, fetA, porB, BAST typing (default=off)
--db DB specify custom directory containing allele databases for porA/fetA typing
directory must contain database files: "FetA_VR.fas", "PorA_VR1.fas", "PorA_VR2.fas"
for Bexsero typing: "fHbp_peptide.fas", "NHBA_peptide.fas", "NadA_peptide.fas", "BASTalleles.txt"
--printseq save porA/fetA or BAST allele sequences to file (default=off)
--updatedb update allele database from <pubmlst.org>
--test run test example
--version show program's version number and exit
Examples
To perform in silico serotyping on FASTA files:
$ meningotype <fasta1> <fasta2> <fasta3> ... <fastaN>`
The serotypes are printed in tab-separated format to stdout
.
To save results to a tab-separated text file, redirect stdout
:
$ meningotype <fasta1> <fasta2> <fasta3> ... <fastaN> > results.txt
To perform in silico serotyping AND finetyping of the porA and fetA genes:
$ meningotype --finetype <fasta1> <fasta2> <fasta3> ... <fastaN>
To save finetyping sequences of the alleles to a file (eg. for uploading "new" sequences to http://pubmlst.org/neisseria/):
$ meningotype --finetype --printseq <fasta1> <fasta2> <fasta3> ... <fastaN>
These are placed into a folder called printseq
in the current directory.
Updating the allele databases
To update the allele databases from http://pubmlst.org/neisseria/
$ meningotype.py --updatedb
A copy of the original database is saved to *.old
just in case,
but is overwritten with each subsequent --updatedb
.
Ensure you back up your old databases if you wish to keep them.
