I am new to working with NGS data. I want to add the information of new Sequence Reads to an existing transcriptome to possibly identify new transcripts. Does anyone have an idea of how to approach the matter? My first idea is mapping the reads to the trancriptome.

Use Tophat and Cufflinks (Trapnell et al. Nature Protocols (2012); http://cufflinks.cbcb.umd.edu/index.html) with the annotation as a guide.
I would not trust it for differential expression of isoforms, but for assembling new transcripts it works fairly well. Only use high quality reads for the assembly and be careful to filter after the final merge.Comment

Data variability is still an issue in sequencing technologies despite the advances in reproducibility and accuracy of these platforms. But the problem does not originate in the sequencing itself, but in the previous steps, before the sample reaches the sequencer.
The first step is collection, followed by preservation and sample preparation for analysis. Most scientists overlook those steps, but not being careful might just be skewing the experiment’s results.

Studying ecosystems means dealing with complex, multi-species communities that are hard to observe at scale. This complexity, however, hides many important questions to be answered, from how biogeochemical cycles work and how climate change can affect species distribution to how conservation strategies can work best.
Genomics, particularly since the expansion of NGS, has transformed ecosystem ecology. By sequencing environmental DNA, we can now assess biodiversity without direct...05-06-2026, 09:04 AM
