fhirizer

Project overview:

Transforms and harmonizes data from Genomic Data Commons (GDC), Cellosaurus cell-lines, and International Cancer Genome Consortium (ICGC) repositories into 🔥 FHIR (Fast Healthcare Interoperability Resources) format.

GDC study simplified FHIR graph

Usage

Installation

from source

git clone repo
cd fhirizer
# create virtual env ex. 
# NOTE: package_data folders must be in python path in virtual envs 
python -m venv venv-fhirizer
source venv-fhirizer/bin/activate
pip install .

Dockerfile

(sudo) docker build -t <tag-name>:latest .
(sudo) docker run -it  --mount type=bind,source=<path-to-input-ndjson>,target=/opt/data --rm <tag-name>:latest

Singularity

singularity build fhirizer.sif docker://quay.io/ohsu-comp-bio/fhirizer
singularity shell fhirizer.sif

Convert and Generate

Detailed step-by-step guide on FHIRizing data for a project's study can be found in the project's directory overview.

GDC

convert GDC schema keys to fhir mapping
generate fhir object models ndjson files in directory

Example run for patient - replace path's to ndjson files or directories.

fhirizer generate --name case --out_dir ./projects/<my-project>/META --entity_path ./projects/<my-project>/cases_key.ndjson

to generate document reference for the patients

fhirizer generate --name file --out_dir ./projects/<my-project>/META --entity_path ./projects/<my-project>/files_key.ndjson

Cellosaurus

Cellosaurus ndjson follows Cellosaurus GET API json format

 fhirizer generate --name cellosaurus --out_dir ./projects/<my-project>/META --entity_path ./projects/<my-project>/<cellosaurus-celllines-ndjson>

ICGC
- NOTE: Active site and data dictionary updates from ICGC DCC to ICGC ARGO is in progress.
```
 fhirizer generate --name icgc --icgc <ICGC_project_name> --has_files
```

Constructing GDC maps cli cmds

initialize initial structure of project, case, or file to add Maps

fhirizer project_init 
# to update Mappings run associated labels script ex ./labels/project.py 

fhirizer case_init 
fhirizer file_init

Testing

pytest -cov

fhirizer structure:

Data directories included in package data:

resources: data resources generated or used in mappings
mapping: json data maps produced by fhirizer pydantic schema maps
