# Select FinnGen data release in Atlas for Search

{% hint style="warning" %}
**Atlas contains several FinnGen data releases**. Please follow these instructions to define the FinnGen data release used in the **Search** and when defining **Concept Sets** using the **Search** functionality\*\*.\*\*

The **Search** is made against the vocabularies (codes) from one FinnGen data release while the number of matching records is shown for a potentially different FinnGen data release. These FinnGen data releases can be defined on the **Configuration** page using the **Vocabulary Version** and **Record Counts** columns.
{% endhint %}

{% hint style="warning" %}
Use the same FinnGen data release to define **Concept Sets** and generate **Cohort Definitions**.
{% endhint %}

{% hint style="info" %}
Use the latest FinnGen data release unless you have a specific reason to use an older release.
{% endhint %}

Follow these instructions to select the FinnGen data release used in Search for vocabularies (codes) and for record counts:

* Select the **Configuration** option on the left menu:

* Select the FinnGen data release for codes from the **Vocabulary Version** column (the FinnGen release is shown in the **Source Name** column). This is the FinnGen data release from where the codes are selected for the **Search**.
* Select the FinnGen data release for record counts from the **Record Counts** column (the FinnGen release is shown in the **Source Name** column). This is the FinnGen data release against which the codes are searched.

In the above screenshot, we have selected the "FinnGen CDM R10" (FinnGen data release 10) for both.

{% hint style="info" %}
Make sure you have selected the **Vocabulary Version** and the **Record Counts** on the same row so that **Search** will show medical codes and counts from the same FinnGen Release.
