FILER Workflow

Getting Started

To get started, click on the Search to search by genomic coordinates, upload and analyze your own data, or click Browse to explore FILER functional genomics datasets and annotations. See Deploy to download and install FILER on a local server or cloud computing instance.

The Summary page provides an overview of FILER data contents by primary data sources, tissue and cell type categories, genomic feature type categories and experimental assays.

The About page provides details on FILER data source curation, data pre-processing and annotation.

Citation & data use

External data users may freely download, analyze and publish results based on any FILER data.
