|Function||Specifies the subsequence of the query to use|
|Example||To search with subsequence between 100-400, use: -L "100,400"|
Convention is -L "start,end", where the start and end are the coordinates for the subsequence. Start position is marked as 1. Coordinates are applied to all queries. If end is larger than the sequence length, sequence length will be used. If start is larger than the sequence length, blast will report error.
