What's the difference between Unaligned and Unmatched in rnaQUAST output?

Question

[lcsousapaula]

In rnaQUAST output, there is an image on topic '4 Understanding rnaQUAST output', which Transcript 1 and 2 are aligned with Genome Reference. But, Transcript 1 has one small fragment which unaligned, called 'Unaligned', on the other hand, the Transcript 2 has a bigger fragment non aligned, however, this one is called 'Unmatched'. What's the difference? Help me, please.
