Examples of various alignment styles:
- Protein alignment with no master set
- Protein alignment, master set to ACI28628
- Protein alignment using FASTA format from the MUSCLE program
- Nucleotide alignment from Blast RID, primate genomic, mRNA, and BAC sequences
- Protein alignment from Blast RID, metazoan proteins belonging to the LIN37 protein family
- Alignment of prion protein sequences from S. cerevisiae PopSet
- Polyprotein alignment with master, Dengue virus 2
- Genomic alignment with consensus, Dengue virus 1
- Alignment of nucleocapsid coding region, Influenza A virus (nonsynonymous substitutions coloring)
- Alignment of polymerase PB1 coding region, Influenza A virus (nonsynonymous substitutions coloring)
