F-Seq
From BITS wiki
Tag sequencing using high-throughput sequencing technologies are now regularly employed to identify specific sequence features such as transcription factor binding sites (ChIP-seq) or regions of open chromatin (DNase-seq). To intuitively summarize and display individual sequence data as an accurate and interpretable signal, we developed F-Seq, a software package that generates a continuous tag sequence density estimation allowing identification of biologically meaningful sites whose output can be displayed directly in the UCSC Genome Browser.

# A perl script has been included which converts data from mapview format (MAQ alignment results) to BED format.
Usage: mapviewToBed.pl <MIN QUAL> <MAX_HITS> <FILE>
MIN_QUAL = Exclude alignments with <= this mapping quality score.
MAX_HITS = Exclude alignments with > this number of hits.
FILE = Mapview file to convert.
Example: perl mapviewToBed.pl 0 2 sequence.mapview
This takes as input sequence.mapview, only uses sequences aligning in fewer than 2 locations with 0 or 1 mismatches, and only sequences with an alignment score of 0 or better.
