# Data Loading

The current version of the loader offers two different loading alternatives: (*v0*) loading of clinical and genomic data based on MAF datasets; and (*v1*) loading of generic i2b2 data. Currently these two loaders support each one dataset:

* *v0*: a genomic dataset (*tcga\_cbio* publicly available in [cBioPortal](http://www.cbioportal.org/))
* *v1*: the [i2b2 demodata](https://www.i2b2.org/software/repository.html?t=demo\&p=15).

Future releases of this software will allow for other arbitrary data sources, given that they follow a specific structure (e.g. BAM format).

## Pre-Requisite: Download test data

From the *medco-deployment* folder, execute the resources/data/download.sh script to download the test datasets.

```bash
cd ${MEDCO_SETUP_DIR}/resources/data
bash download.sh
```

## Dummy Generation

The provided example data set files come with dummy data pre-generated. Those data are random dummy entries whose purpose is to prevent frequency attacks. In a future release, the generation will be done dynamically by the loader.

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://ldsec.gitbook.io/medco-documentation/v0.3.0/system-administrators/data-loading.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
