# postprocessing
`postprocess.py` executes Cypher queries to create mappings between MeSH, UMLS, MDM, and ClinicalTrials.gov data in a Neo4j graph database.

The main script `postprocess.py` runs a set of predefined Cypher queries for:
* mapping MeSH terms to UMLS concepts
* mapping MDM Portal aliases to UMLS concepts
* mapping ClinicalTrials.gov studies to MeSH terms
* mapping ClinicalTrials.gov studies to MDM Portal entries

## Quickstart

Create a configuration file with your Neo4j connection details.  
For example, save it as `postprocess.conf`:

```ini
[neo4j]
uri = bolt://localhost:7687
username = neo4j
password = myfancypassword
```

Run the postprocessing by providing the configuration file:
```sh
python3 src/postprocess.py --conf ~/postprocess.conf
```

## Requirements

* make sure `python3` is installed
* have a running Neo4j instance (version 5)
* the Neo4j instance must have the APOC plugin installed
* create the configuration file as described in the [Quickstart](#quickstart) section
