 CHM-eval, aka Syndip, is a benchmark dataset for evaluating the accuracy of
 small variant callers. It is constructed from the PacBio assembilies of two
-independent [CHM][CHM] cell lines and is largely orthogonal to the methodology
-used for short-read variant calling, which makes it more comprehensive and less
-biased in comparison to existing benchmark datasets. The following figure
-briefly explains how this dataset was generated:
