Dear Geng Chen

Yes. Note that DEXSeq

1. finds those genes in which isoforms are differentially expressed

2. within those genes, tries to determine which exons are affected in 
particular. This works well for genes with many exons, where the 
differential expression only affects a few exons.

DEXSeq does not attempt to solve the isoform deconvolution problem.
