Proportion of reads backmapping to each transcriptome assembly. SOAPdenovo-Trans (1): no filtering; (2): light filtering of poor quality read pairs, combined with in silico normalization; (3): moderate filtering of poor quality read pairs; Velvet/Oases: moderate filtering of poor quality read pairs; Trinity (1): light filtering of poor quality read pairs, combined with in silico normalization; (2): light filtering of poor quality read pairs, combined with SEECER error correction; (3): moderate filtering of poor quality read pairs; (4): moderate filtering of poor quality reads and SEECER error correction; tr2aacds merged assemblies (1): pre-v2.3.2 Trinity; (2): including v2.3.2 Trinity.
