If I understand you correctly you're looking at the trace data (multiple points per peak) and comparing to the base calls (one call per peak). In my experience folks interested in the chromatogram would prefer to see an image with the chromatogram spaced properly, those primarily interested in the base calls prefer to have the chromatogram scaled around a fixed width for the basecall. There's code to do either in BioJava, but the former might not be setup to generate a BufferedImage (if you can't find it I might be able to help some). _______________________________________________ Biojava-l mailing list - [email protected] http://lists.open-bio.org/mailman/listinfo/biojava-l
