- trims vector only at 5' end
- call lucy trimming for qualities
Lucy
- both vector sequence and splice sites are required
Atlas

Vector/Splice site search
- Select all the reads in the same volume that belong to one particular library; same CENTER_NAME, STRATEGY & TRACE_TYPE_CODE
- Get the quality clipping time: CLIP_QUALITY_LEFT & CLIP_QUALITY_RIGHT
- Separate reads in 2 piles according to direction TRACE_END: FORWARD & REVERSE
- Get the most frequent kmers (24 & 8 bp)
- Check if the most frequent kmers are overrepresented
- Check if the most frequent 8mers are part of the most frequent 24mers
- Try to extend the kmers by a few bp => linkers
- Align linkers to the opposite stand sequences
- Extract the sequences adjacent(following) to linker (50..150bp)
- Align the sequences; if they align we've probably identified the vector
- Align the vector to UniVec => several alignments
- Check if the forward/reverse vector(s) are the same : should find a common vector sequence; the UniVec alignments should be adjacent
- create the Lucy vector & splice files
