tRNAscan-SE employs
  1. a modified, optimized version of tRNAscan v1.3 (Fichant & Burks, J. Mol. Biol. 220: 659-671, 1991),
  2. a new implementation of a multistep weight matrix algorithm for identification of eukaryotic tRNA promoter regions (Pavesi et al., Nucl. Acids Res. 22: 1247-1256, 1994),
  3. the RNA covariance analysis package Cove v.2.4.2 (Eddy & Durbin, Nucl. Acids Res. 22: 2079-2088, 1994)
