DESCRIPTION¶

convert-pheno is a command-line front-end to the CPAN's module Convert::Pheno.

SUMMARY¶

A script that uses Convert::Pheno to interconvert common data models for phenotypic data

INSTALLATION¶

If you plan to only use the 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's). 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 libbz2-dev zlib1g-dev libperl-dev libssl-dev

Now you have two choose between one of the 3 options below:

Option 1: System-level installation:

cpanm --notest --sudo Convert::Pheno
convert-pheno -h

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

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

Option 3: Install Convert-Pheno and the dependencies in a "virtual environment" (at local/) . We'll be using the module Carton for that:

mkdir local
cpanm --notest --local-lib=local/ Carton
echo "requires 'Convert::Pheno';" > cpanfile
export PATH=$PATH:local/bin; export PERL5LIB=$(pwd)/local/lib/perl5:$PERL5LIB
carton install
carton exec -- convert-pheno -help

Method 2: From CPAN in a Conda environment¶

Please follow these instructions.

Method 3: From Github¶

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

Install system level dependencies:

sudo apt-get install cpanminus libbz2-dev zlib1g-dev libperl-dev libssl-dev

Now you have two choose between one of the 3 options below:

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

cpanm --notest --sudo --installdeps .
bin/convert-pheno --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/convert-pheno --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

Option 3: Install the dependencies in a "virtual environment" (at local/) . We'll be using the module Carton for that:

mkdir local
cpanm --notest --local-lib=local/ Carton
export PATH=$PATH:local/bin; export PERL5LIB=$(pwd)/local/lib/perl5:$PERL5LIB
carton install
carton exec -- bin/convert-pheno -help

Containerized¶

Method 4: From Docker Hub¶

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

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

See additional instructions below.

Method 5: With Dockerfile¶

Please download the Dockerfile from the repo:

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

And then run:

docker buildx build -t cnag/convert-pheno:latest .

Additional instructions for Methods 4 and 5¶

To run the container (detached) execute:

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

To enter:

docker exec -ti convert-pheno bash

The command-line executable can be found at:

/usr/share/convert-pheno/bin/convert-pheno

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

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

Alternatively, you can use make to perform all the previous steps:

wget https://raw.githubusercontent.com/cnag-biomedical-informatics/convert-pheno/main/Dockerfile
wget https://raw.githubusercontent.com/cnag-biomedical-informatics/convert-pheno/main/makefile.docker
make -f makefile.docker install
make -f makefile.docker run
make -f makefile.docker enter

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 convert-pheno-mount cnag/convert-pheno:latest

Then I will do something like this:

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

# Now I use the alias to run the command (note that I use the flag --out-dir to specify the output directory)
convert-pheno -ibff /data/individuals.json -opxf pxf.json --out-dir /data

System requirements¶

* Ideally a Debian-based distribution (Ubuntu or Mint), but any other (e.g., CentOs, OpenSuse, MacOS) 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 CONVERT-PHENO¶

For executing convert-pheno you will need:

Input file(s):

A text file in one of the accepted formats. With --iomop I/O files can be gzipped.
Optional:

Athena-OHDSI database

The database file is available at this link (~2.2GB). The database may be needed when using -iomop.

Regardless if you're using the containerized or non-containerized version, the download procedure is the same. For CLI users, Google makes it difficult to use wget, curl or aria2c so we will use a Python module instead:
```
$ pip install gdown
```
And then run the following script
```
import gdown

url = 'https://drive.google.com/uc?export=download&id=1-Ls1nmgxp-iW-8LkRIuNNdNytXa8kgNw'
output = './ohdsi.db'
gdown.download(url, output, quiet=False)
```
Once downloaded, you have two options:

a) Move the file ohdsi.db inside the share/db/ directory.

or

b) Use the option --path-to-ohdsi-db

Examples:

$ bin/convert-pheno -ipxf phenopackets.json -obff individuals.json

$ $path/convert-pheno -ibff individuals.json -opxf phenopackets.yaml --out-dir my_out_dir

$ $path/convert-pheno -iredcap redcap.csv -opxf phenopackets.json --redcap-dictionary redcap_dict.csv --mapping-file mapping_file.yaml

$ $path/convert-pheno -iomop dump.sql -obff individuals.json

$ $path/convert-pheno -iomop dump.sql.gz -obff individuals.json.gz --stream -omop-tables measurement -verbose

$ $path/convert-pheno -cdisc cdisc_odm.xml -obff individuals.json --rcd redcap_dict.csv --mapping-file mapping_file.yaml --search mixed --min-text-similarity-score 0.6

$ $path/convert-pheno -iomop *csv -obff individuals.json -sep ','

$ carton exec -- $path/convert-pheno -ibff individuals.json -opxf phenopackets.json # If using Carton

COMMON ERRORS AND SOLUTIONS¶

* Error message: CSV_XS ERROR: 2023 - EIQ - QUO character not allowed @ rec 1 pos 21 field 1
  Solution: Make sure you use the right character separator for your data with --sep <char>. 
            The script tries to guess it from the file extension, but sometimes extension and actual separator do not match. 
            When using REDCap as input, make sure that <--iredcap> and <--rcd> files use the same separator field.
            The defauly value for the separator is ';'. 
  Example for tab separator in CLI.
   --sep  $'\t'

* Error message: Foo
  Solution: Bar
