Sequence Identity And Similarity

Plea for Support

If you've found SIAS useful for your research, please the SECRETARIA GENERAL DE CIENCIA, TECNOLOGIA E INNOVACION OF SPAIN (sgcti@mineco.es, dgi@mineco.es). Thank you.
Your support is crucial to keep the site up and running.

SIAS calculates pairwise sequence identity and similarity from multiple sequence alignments

 

INPUT
MSA
Paste your alignment (CLUSTAL, FASTA or GCG/PileUp format)

or Upload a file with the alignment in CLUSTAL, FASTA or GCG/PileUp format

 

IDENTITY (ID) & SIMILARITY (SIM) PERCENTAGE
OPTIONS
SIMILARITY AMINO ACID GROUPING
Aromatic: H
Aliphatic: L
Charged positive: H
Charged negative: E
Small:
Polar (Not charged): S

SEQUENCE LENGTH
Length of smallest sequence Length of largest sequence
Mean length of sequences Length of Multiple Sequence Alignment

 

NORMALIZED SIMILARITY SCORE
OPTIONS
Select a matrix:
BLOSUM62

GONNET
Select gap penalties:
  • Cost for creating the gap, Po (0-100)
  • Cost for extending the gap, Pe (0-100)
