OligoFragger enables spectrum graph-guided identification of modified RNA oligonucleotides from tandem mass spectrometry, increasing identifications under stringent FDR control in Escherichia coli and human tRNA datasets.
- Why it matters: Dense tRNAs contain multiple modified residues and many chemistries, making comprehensive identification difficult because database searches must consider dozens of modification candidates at once.
- What they did: The method uses fragment evidence to constrain modified-oligonucleotide searches before full database scoring, and it is tested on controlled RNA samples and tRNA datasets from Escherichia coli and human cells.
- The result: OligoFragger recovers known modification patterns and supports label-free quantification while maintaining sensitive, FDR-controlled identification in complex epitranscriptomic search spaces.
