Definition of Positive and Negative is inconsistent with Fig 3 for 'Right' Alternative Terminal Exon Events

[lzx325]

According to the code of this member function of class ALTR in lib/event.py,

SUPPA/lib/event.py

Lines 309 to 319 in 1c0ad91

	def create_altr(self, coord1, coord2, coord3, transcript):
	"""
	Find and create alternative events
	"""
	gene = self.gene
	for neg1, neg2, neg3 in self.negative_coords:
	if neg1 == coord1 and neg2 > coord3:
	eventid = '{}:{}-{}:{}:{}-{}:{}:{}'.format(gene.chr, coord1, coord2, coord3,
	neg1, neg2, neg3, gene.strand)
	self.positive_ids[eventid] = self.positive_ids.get(eventid, []) + [transcript]
	self.negative_ids[eventid] = self.negative_coords[(neg1, neg2, neg3)]

Since neg2 > coord3 is guaranteed at L315, the right terminal exon of transcript lies to the left of the exon (neg2,neg3). Therefore, the variable transcript does not denote the isoform containing the 'black exon' in Figure 3. I think the rhs of L318 and L319 should be switched. Am I right?
