obsolete genomic position true remodeling notion of sequence feature position around the idea of a 'genomic locus' This 'genomic position' concept differs from the faldo:Position concecpt in that the former describes the start AND end points/coordinates of a feature, while the latter describes a single point/coordinate at the beginning OR end of a feature.
