While you are awaiting your dbGap approval, it is recommended that you head to the Seven Bridges Cancer Genomics Cloud, and register a new account. Note that you will do so with the same ERA Commons account used to submit your dbGaP application.

+

!!NOTE: dbGaP approval for HTAN study phs002371 is required in order to access HTAN lower-level genomics data, such as RNAseq FASTQ and BAM files.

Once your dbGaP application has been approved, you can access HTAN data via the Cancer Data Service browser within the Seven Bridges Cancer Genomics Cloud. To do so, head to Seven Bridges Cancer Genomics Cloud, and log in with your ERA Commons credentials.

Once logged in, navigate to the top navigation bar, and select Data > Cancer Data Service Explorer.
