trnascan-se website  

tRNA detection in large-scale genome sequences. tRNAscan-SE detects ~99% of eukaryotic nuclear or prokaryotic tRNA genes, with a false positive rate of less than one per 15 gigabases, and with a search speed of about 30 kb/second. It was implemented for large-scale human genome sequence analysis, but is applicable to other DNAs as well. It applies our COVE software (see below) with a carefully built tRNA covariance model, while getting around COVE's speed limitations by using two tRNA finding programs from other research groups as fast first-pass scanners (Fichant and Burks', and an implementation of an algorithm from A. Pavesi's group). It runs on any UNIX system with Perl and a C compiler installed.
