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 symbolsTA.ins_S:123:?will match any insertion, at position 123 on gene S
