At PlantGDB, efforts are undertaken to identify and remove all contaminant DNA so that a clean dataset is made available to researchers. Here, we use the Vmatch program (with options -d -p -l 50 -exdrop 1 -identity 90) to screen EST sequences against UniVec for vector contaminations . The table below summarizes the total count of "contamination". Clicking on the count will browse the individual contaminated sequence.
