Insertion filters

It is possible to filter for amino acid and nucleotide insertions. Multiple insertion filters can be provided in a single request.

A nucleotide insertion has the format ins_<position>:<insertion>. A <insertion> can be a string of one or more of the four nucleotides A, T, C, G or the ambiguous symbols. Example: ins_123:TAT

An amino acid insertion has the format ins_<gene>:<position>:<insertions>. The following genes are available: E, M, N, ORF1a, ORF1b, ORF3a, ORF6, ORF7a, ORF7b, ORF8, ORF9b, S. A <insertions> can be a string of one or more of the 20 amino acid codes, or ambiguous symbols. Example: ins_E:123:QE

Wildcard

Both insertion filters support a search if the insertion is not known (entirely). In the insertion you can add ? at a position, where you expect any or multiple insertions.

Examples:

  • ins_S:123:?TA? will match any insertion, at position 123 on gene S that has an insertion that contains the symbols TA.
  • ins_S:123:? will match any insertion, at position 123 on gene S
