SUMMARY¶

Pheno-Ranker is a lightweight, easy-to-install tool for performing semantic similarity analysis on phenotypic data in JSON/YAML formats, including Beacon v2 Models and Phenopackets v2. It also supports pre-processed CSV files prepared using the included csv2pheno-ranker utility.

INSTALLATION¶

If you plan to only use pheno-ranker CLI, we recommend installing it via CPAN. See details below.

Non containerized¶

The script runs on command-line Linux and it has been tested on Debian/RedHat/macOS based distributions (only showing commands for Debian). Perl 5 is installed by default on Linux, but we will install a few CPAN modules with cpanminus.

Method 1: From CPAN¶

First install system level dependencies:

sudo apt-get install cpanminus libperl-dev

Now you have to choose between one of the 2 options below:

Option 1: System-level installation:

cpanm --notest --sudo Pheno::Ranker
pheno-ranker -h

Option 2: Install Pheno-Ranker and the dependencies at ~/perl5

cpanm --local-lib=~/perl5 local::lib && eval $(perl -I ~/perl5/lib/perl5/ -Mlocal::lib)
cpanm --notest Pheno::Ranker
pheno-ranker --help

To ensure Perl recognizes your local modules every time you start a new terminal, you should type:

echo 'eval $(perl -I ~/perl5/lib/perl5/ -Mlocal::lib)' >> ~/.bashrc

Method 2: From CPAN in a CONDA environment¶

Please follow these instructions.

Method 3: From GitHub¶

git clone https://github.com/cnag-biomedical-informatics/pheno-ranker.git
cd pheno-ranker

Install system level dependencies:

sudo apt-get install cpanminus libperl-dev

Now you have to choose between one of the 2 options below:

Option 1: Install dependencies (they're harmless to your system) as sudo:

cpanm --notest --sudo --installdeps .
bin/pheno-ranker --help

Option 2: Install the dependencies at ~/perl5:

cpanm --local-lib=~/perl5 local::lib && eval $(perl -I ~/perl5/lib/perl5/ -Mlocal::lib)
cpanm --notest --installdeps .
bin/pheno-ranker --help

To ensure Perl recognizes your local modules every time you start a new terminal, you should type:

echo 'eval $(perl -I ~/perl5/lib/perl5/ -Mlocal::lib)' >> ~/.bashrc

Optional: If you want to use utils/barcode or utils/bff_pxf_plot:

sudo apt-get install python3-pip libzbar0
pip3 install -r requirements.txt

Containerized¶

Method 4: From Docker Hub¶

Download a docker image (latest version - amd64|x86-64) from Docker Hub by executing:

docker pull manuelrueda/pheno-ranker:latest
docker image tag manuelrueda/pheno-ranker:latest cnag/pheno-ranker:latest

See additional instructions below.

Method 5: With Dockerfile¶

Please download the Dockerfile from the repo:

wget https://raw.githubusercontent.com/cnag-biomedical-informatics/pheno-ranker/main/Dockerfile

And then run:

# Docker Version 19.03 and Above (Supports buildx)
docker buildx build -t cnag/pheno-ranker:latest .

# Docker Version Older than 19.03 (Does Not Support buildx)
docker build -t cnag/pheno-ranker:latest .

Additional instructions for Methods 4 and 5¶

To run the container (detached) execute:

docker run -tid -e USERNAME=root --name pheno-ranker cnag/pheno-ranker:latest

To enter:

docker exec -ti pheno-ranker bash

The command-line executable can be found at:

/usr/share/pheno-ranker/bin/pheno-ranker

The default container user is root but you can also run the container as $UID=1000 (dockeruser).

 docker run --user 1000 -tid --name pheno-ranker cnag/pheno-ranker:latest

Mounting volumes¶

Docker containers are fully isolated. If you need the mount a volume to the container please use the following syntax (-v host:container). Find an example below (note that you need to change the paths to match yours):

docker run -tid --volume /media/mrueda/4TBT/data:/data --name pheno-ranker-mount cnag/pheno-ranker:latest

Then I will do something like this:

# First I create an alias to simplify invocation (from the host)
alias pheno-ranker='docker exec -ti pheno-ranker-mount /usr/share/pheno-ranker/bin/pheno-ranker'

# Now I use the alias to run the command (note that I use the flag --o to specify the filepath)
pheno-ranker -r /data/individuals.json -o /data/matrix.txt

System requirements¶

* Ideally a Debian-based distribution (Ubuntu or Mint), but any other (e.g., CentOS, OpenSUSE) should do as well.
  (It should also work on macOS and Windows Server, but we are only providing information for Linux here)
* Perl 5 (>= 5.26 core; installed by default in most Linux distributions). Check the version with "perl -v".
* >= 4GB of RAM
* 1 core
* At least 16GB HDD

HOW TO RUN PHENO-RANKER¶

For executing pheno-ranker you will need a PXF/BFF file(s) in JSON|YAML format. The reference cohort must be a JSON array, where each individual data are consolidated in one object.

You can download examples from this location.

There are two modes of operation:

Cohort mode:

Intra-cohort: With --r argument and 1 cohort.

Inter-cohort: With --r and multiple cohort files. It can be used in combination with --append-prefixes to add prefixes to each individual id.
Patient Mode:

With -r reference cohort(s) and --t patient data.

Examples:

$ ./pheno-ranker -r phenopackets.json  # intra-cohort

$ ./pheno-ranker -r phenopackets.yaml -o my_matrix.txt # intra-cohort

$ ./pheno-ranker -r phenopackets.json -w weights.yaml --exclude-terms sex ethnicity exposures # intra-cohort with weights

$ $path/pheno-ranker -r individuals.json others.yaml --append-prefixes CANCER CONTROL  # inter-cohort

$ $path/pheno-ranker -r individuals.json -t patient.yaml -max-out 100 # mode patient

COMMON ERRORS AND SOLUTIONS¶

* Error message: R plotting
    Error in scan(file = file, what = what, sep = sep, quote = quote, dec = dec,  : 
    line 1 did not have X elements
    Calls: as.matrix -> read.table -> scan
    Execution halted
  Solution: Make sure that the values of your primary key (e.g., "id") do not contain spaces (e.g., "my fav id" must be "my_fav_id")

* Error message: Foo
  Solution: Bar
