What it does
The main purpose of this tool is to extract continuous ACGT sequences from scaffolds, thereby breaking scaffolds at 'N' regions.
For example, if the scaffold sequence is:
ATGCCGTAGATTGAAGCAGAGGGCCGNNNNNNNNNNNNTAGATACAGGTTGCTCTAGACAGAG
Then this scaffold will be broken into two sequences:
ATGCCGTAGATTGAAGCAGAGGGCCG and TAGATACAGGTTGCTCTAGACAGAG
