Protein Variability Server

User Guide	Variability Methods	Input	Output

This server calculates the sequence variability within a multiple sequence alignment using several variability metrics. Subsequently, the server can perform several tasks, such as masking the variability in the reference sequence, returning conserved fragments or mapping the sequence variability onto a provided 3D-structure.
