# the strong interactions here are called from the annotation of RNA (whole RNA)
# for each cell type, there are two columns, # the first column gives the number of strong interactions with this interaction type, # the second column gives the number of mapped pairs that support this interaction type
Interaction type	E14 (UV)		MEF
	# of Interaction	# of mapped pairs	# of Interaction	# of mapped pairs
