AA mutation frequency

For each class, the frequency of replacement mutations at each amino acid position is shown, which is calculated by dividing the number of replacement mutations at a particular amino acid position/the number sequences that have an amino acid at that particular position. Since the length of the CDR1 and CDR2 region is not the same for every VH gene, some amino acids positions are absent. Therefore we calculate the frequency using the number of amino acids present at that that particular location.

Antigen selection (BASELINe)

Shows the results of the analysis of antigen selection as performed using BASELINe. Details on the analysis performed by BASELINe can be found in Yaari et al, PMID: 22641856. The settings used for the analysis are: focused, SHM targeting model: human Tri-nucleotide, custom bounderies. The custom boundries are dependent on the ‘sequence starts at filter’.
