Genomic DNA used as a template for in vitro transcription of RNA can serve as a true negative control for RNA modification detection in Nanopore direct RNA sequencing (DRS) data. We generated DRS for IVT RNA composed of canonical nucleotides using genomic DNA templates. We applied Dorado modification calling models to these data, which allowed for the calculation of 9-mer specific false positive rates for a set of RNA modifications. These false positive rates capture the complete set of 9-mer sequence contexts and can be applied to a broad range of experimental conditions.

"Similar papers" are the closest papers from that journal in the model's embedding space. They show what the match is built on, but the ranking comes mostly from a classifier over the whole training set, not from these examples alone.
