Also, future versions of FINDER will offer functionalities to leverage data from CAGE-Seq and Ribo-Seq to better annotate transcription start site and translation start sites respectively. BRAKER2 was configured to optimally predict only CDS regions of genes, hence, it performs well with the set of transcripts that have missing UTRs for organisms with small and moderate sized genomes (Fig. 2018;34:422331.

Annotation gives meaning to a given sequence and makes it much easier for researchers to view and analyze its contents. Decoding the correct structures of genes is essential since several downstream applications rely on accurate annotations: detecting interactions between proteins [6,7,8,9,10,11,12,13,14], identifying post-translational modifications [15,16,17,18,19,20,21,22,23], mining effectors [24,25,26,27,28], and determining protein structure [29,30,31,32].

This demonstrates that FINDER is capable of effectively constructing genes from different evolutionary backgrounds.

Tools such as MAKER [42,43,44,45] and PASA [36] closely depend on pre-assembled full-length transcripts to generate annotations. As shown in Table 4 and Additional file 6: Table S5, implementing the CPD improved both specificity and sensitivity in organisms with small or medium-sized genomes. ESTs and/or de novo assembled transcriptomes have been often provided as inputs to these tools to generate annotations [46,47,48,49,50,51,52]. Bioinformatics.
