Bioinformatics (Oxford, England)
|August 29, 2001
Summary
The study evaluated the multiple alignment quality of SAM-T99, a hidden Markov model tool for protein sequence analysis. Results show SAM-T99 is as accurate as CLUSTALW for generating multiple sequence alignments.
Area of Science:
- Bioinformatics
- Computational Biology
- Genomics
Background:
- SAM-T99 is a hidden Markov model (HMM)-based method for identifying homologous protein sequences and generating multiple sequence alignments.
- Previous evaluations focused on search quality, not multiple alignment accuracy.
- This study specifically assesses the multiple alignment performance of SAM-T99.
Purpose of the Study:
- To evaluate the multiple alignment quality of the SAM-T99 protocol.
- To compare the performance of SAM-T99 against CLUSTALW, a standard multiple sequence alignment tool.
Main Methods:
- Utilized the BAliBASE benchmark alignment database for evaluation.
- Compared the accuracy of SAM-T99's multiple alignments with CLUSTALW.
Main Results:
- SAM-T99 demonstrated comparable accuracy to CLUSTALW on the BAliBASE benchmarks.
- The evaluation focused on the multiple alignment aspect of the SAM-T99 protocol.
Conclusions:
- SAM-T99 is a viable tool for generating high-quality multiple sequence alignments.
- Its performance in multiple alignment is on par with established tools like CLUSTALW.
