Sam’s Notebook: Transcriptome Annotation – Trinotate C.bairdi MEGAN6 Taxonomic-specific Trinity Assembly on Mox

After performing de novo assembly on our Tanner crab MEGAN6 taxonomic-specific RNAseq data on 20200122 and performing BLASTx annotation on 20200123, I continued the annotation process by running Trinotate.

Trinotate will perform functional annotation of the transcriptome assembly, including GO terms and an annotation feature map that can be used in subsequent Trinity-based differential gene expression analysis so that functional annotations are carried downstream through that process.
