trimetass website  

TriMetAss is an extension to the Trinity software [1], which can assemble select regions surrounding interesting features in metagenomic data. The software is particularly useful for very common and well-conserved genes (and – in theory – non-coding regions) that can occur in multiple contexts in the microbial community under study. It uses Vmatch [2] to extend seed reads (or contigs generated by another assembler) into longer contigs, by iteratively calling Vmatch and Trinity, until some stop criteria are met.
