Range Extractor DNA
Range Extractor DNA accepts a DNA sequence along with a set of positions or ranges. The bases corresponding to the positions or ranges are returned, either as a single new sequence, a set of FASTA records, as uppercase text, or as lowercase text. Use Range Extractor DNA to obtain subsequences using position information.

Paste a raw sequence or one or more FASTA sequences into the text area below. Input limit is 500000 characters.

Enter the base positions or ranges to be extracted. Use ".." to represent a range, and use a comma to separate entries. The words 'start', 'end', 'center', and 'length' can be used in place of digits, to represent the beginning, end, middle, and length of the sequence. Arithmetic expressions can be included in the ranges. For example, to obtain the last three bases of a sequence, the range '(end - 2)..end' can be used. To obtain the 30 bases on either side of the center base along with the center base, the ranges '(center - 30)..(center - 1), center, (center + 1)..(center + 30)' can be used.

Please check the browser compatibility page before using this program.
