% pip3 install mob_suite
```

### Source
For system-wide installation one can follow these commands on Ubuntu distro that includes Python
library dependencies and tools
```bash
apt update && apt install python3-pip #installs gcc compiler for pycurl
apt install libcurl4-openssl-dev libssl-dev #for pycurl
pip3 install Cython
apt install mash ncbi-blast+
python3 setup.py install && mob_init #to install and init databases
```

### Docker image
A docker image is also available at [https://hub.docker.com/r/kbessonov/mob_suite](https://hub.docker.com/r/kbessonov/mob_suite)

```
% docker pull kbessonov/mob_suite:3.0.1
% docker run --rm -v $(pwd):/mnt/ "kbessonov/mob_suite:3.0.1" mob_recon -i /mnt/assembly.fasta -t -o /mnt/mob_recon_output
% docker pull kbessonov/mob_suite:3.0.3
% docker run --rm -v $(pwd):/mnt/ "kbessonov/mob_suite:3.0.3" mob_recon -i /mnt/assembly.fasta -t -o /mnt/mob_recon_output
```

### Singularity image
A singularity image could be built via singularity recipe donated by Eric Deveaud.
The recipe (`recipe.singularity`) is located in the singularity folder of this repository.
The docker image [README section](https://hub.docker.com/repository/docker/kbessonov/mob_suite) also has instructions on how to create singularity image from a docker image.
A singularity image could be built locally via Singularity recipe donated by Eric Deveaud.
The recipe (`recipe.singularity`) is located in the `singularity` folder of this repository and installs MOB-Suite via `conda`.

```bash
% singularity build mobsuite.simg recipe.singularity
```

In addition, Singularity currently supports docker images and automatically converts them to Singularity images format.
```bash
% singularity pull docker://kbessonov/mob_suite:3.0.3
```

Alternatively, Singularity image can be pulled from [BioContainers repository](https://biocontainers.pro/tools/mob_suite) where `<version>` is
the desired version (e.g. `3.0.3--py_0`)

```bash
% singularity run https://depot.galaxyproject.org/singularity/mob_suite:<version>

## Using MOB-typer to perform replicon and relaxase typing of complete plasmids and predict mobility

You can perform plasmid typing using a fasta formated file containing a single plasmid represented by one or more contigs or it can treat all of the sequences in the fasta file as independant. The default behaviour is to treat all sequences in a file as from one plasmid, do not include multiple unrelated plasmids in the file without specifying --multi as they will be treated as a single plasmid.

As of v. 3.0.0, we have added the ability of users to provide their own specific set of sequences to remove from plasmid reconstruction. This should be performed with caution and with the knowlede of your organism. Sequences which are frequently of plasmid origin but are not in your organism is the primary use case we envision for this feature.

As of v. 3.0.0, we have provided the ability to use a collection of closed genomes which will be quickly checked using Mash for genomes which are genetically close and limit blast searches to those chromosomes. This more nuanced and automatic approach is recommended for users where there are sequences which should be filtered in one genomic context but not another. We provide as an optional download as set of closed Enterobacteriacea genomes from NCBI which can be used to provide added accuracy for some organisms such as E. coli and Klebsiella where there are sequences which switch between chromosome and plasmids.

If reconstructed plasmids exceed the Mash distance for primary cluster assignment, then they will get assigned a name in the format novel_{md5} where the md5 hash is calculated based on all of the sequences belonging to that reconstructed plasmid. This will provide a unique name for them but any change will result in a changed in the md5 hash. It is inadvised to use these groups for further analyses. Rather they should be highlighted as cases where targeted long read sequencing is required to obtain a closer database representitive of that plasmid.

## Using MOB-cluster
Use this tool only to update the plasmid databases or build a new one and should only be completed with closed high quality plasmids. If you add in poor quality data it can severely impact MOB-recon. As od v. 3.0.0, MOB-cluster has been re-written to utilize the output from MOB-typer to greatly speed up the process of updating and builing plasmid databases by using pre-computed results. Clusters generated from earlier versions of MOB-suite are not compatibile with the new clusters. We have povided a mapping file of previous cluster assignments and their new cluster accessions. Each cluster code is unique and will not be re-used.
