tRNA-derived SINEs are found in a number of eukaryotes especially mammalian genomes. After manual inspection and analysis, we apply the following filter to this genome for eliminating these tRNA-derived elements from true tRNAs. If the tRNA candidates have hits in both tRNAscan and Eufind first-pass scanners, we use a combination of at least 20 bits COVE score, 10 bits HMM score, and 5 bits 2' structure score to define a true tRNA. If the tRNA candidates only have hits in one of the first-pass scanners, the threshold of a true tRNA will be 55 bits COVE score.
