# Phenotypic Filtering
To filter with phenotypic data, you can filter from the tiles that you added in the “Overview” tab, or through the “+ Add Filter” button in the Cohort Banner. These filters allow for assessing the impact of phenotypic/ clinical data and the creation of cohorts.
## How to Filter a Dataset with Phenotypic Filters
1\. In the Cohort section, select the “+ Add Filter”
2\. Search or select your characteristic. Ex: Diagnoses, Tumor Details > Tumor Disease Anatomic Site
3\. Click Add Cohort Filter
4\. Make sure "Is Any of" is selected, click on empty field
5\. Select details for the characteristic. Ex: selecting Ovary
6\. Your cohort panel will then look like this:
7. Repeat steps as necessary to filter as needed to create your cohort
## **And/ Or Functionality**
In this example, we are going to create 2 different filters. One will be a sample with where the tumor disease anatomic site is the ovary, and another where the site is breast.
If in the cohort filter we select the tumor disease anatomic site “is ovary” AND tumor disease anatomic site “is breast”, then we have zero patients.
This is seen the in the figure below:
Instead, we would need to change this to “OR” by pressing the “AND With” portion of the filter.
Now, we have a filter that has the tumor disease anatomic site as the ovary or the breast.
