To visualize 4C-seq data on to the WashU EpiGenome Browser follow the next steps:

	-Go to the Washu EpiGenome Browser Legacy webpage: http://epigenomegateway.wustl.edu/legacy/

	-Selected and load the Mouse mm9 genome.

	-Go to the Genome Browser.

	-In the right upper part of the browser display the Apps panel and select Session option.

	-Upload the desired session.

Sessions are named by the nearest gene to the viewpoint, hereby the following sessions are available:
	
	-session_PITX2_VP1 (equivalent region to human 4q25 locus)
	-session_PITX2_VP2 (equivalent region to human 4q25 locus)
	-session_PITX2_VP3 (equivalent region to human 4q25 locus)
	-session_PRRX1_VP1 (equivalent region to human 1q24 locus)
	-session_PRRX1_VP2 (equivalent region to human 1q24 locus)
	-session_ZFHX3_VP (equivalent region to human 16q22 locus)
	-session_SYNE2_VP (equivalent region to human 14q23 locus)
	-session_CAV1_VP (equivalent region to human 7q31 locus)

	*Equivalent region to human 1q21 locus is not provided do to the lack of reproducibility between replicates for this viewpoint.

Legend for the tracks displayed in the sessions:

	-aur: atria samples
	-ven: ventricle samples
	-Refseq genes: mouse genome NIH reference sequence genes.
	-Matplot wrap: overlap for normalized reads profiles of two replicates atria or ventricles (to show each profile alone Marplot can be cancelled with the left bottom 	of the mouse).
	-ONLY_sig_frag: track showing significative 4C fragments.
	-sig_frag: arc plot showing significative interactions between the viewpoint and the contacted region.
	-S0,S10,S20: sliding windows of 30 fragments showing Z-score values. Fragments with Z-score > 2 are considered as a significative interaction.
