The C. savignyi genome was provided by the Broad Institute at MIT and Harvard.
The strand information (+/-) for this track is in two parts. The first + or - indicates the orientation of the query sequence whose translated protein produced the match. The second + or - indicates the orientation of the matching translated genomic sequence. Because the two orientations of a DNA sequence give different predicted protein sequences, there are four combinations. ++ is not the same as --; nor is +- the same as -+.
The alignments were done with blat in translated protein mode requiring 2 nearby 4-mer matches to trigger a detailed alignment. The $organism genome was masked with RepeatMasker and Tandem Repeat Finder before running blat.
