Function

Sequence with HMM (ClustalO wrapper)

Description

eomegash is a wrapper to clustalo. It takes a set of unaligned sequences and one HMM and produces a combined output alignment.

Clustal-Omega (clustalo) is a general purpose multiple sequence alignment (MSA) program for proteins. It produces high quality MSAs and is capable of handling data-sets of hundreds of thousands of sequences in reasonable time.

In its current form Clustal-Omega can only align protein sequences but not DNA/RNA sequences. It is envisioned that DNA/RNA will become available in a future version.

Algorithm

Clustal-Omega uses HMMs for the alignment engine, based on the HHalign package from Johannes Soeding [1]. Guide trees are optionally made using mBed [2] which can cluster very large numbers of sequences in O(N*log(N)) time. Multiple alignment then proceeds by aligning larger and larger alignments using HHalign, following the clustering given by the guide tree.
