Experiment: Dodecandioic (C)
Only strains with sufficient reads to estimate fitness are shown,
but the strain fitness values are still rather noisy and may be biased towards zero.
Strains near the edge of a gene are not shown as being associated with that
gene (they are in grey).
Strains in the central 10-90% of a gene are color coded by the insertion's strand.
Usually, "+" means that the selectable marker is encoded on the forward strand,
i.e., transcribed rightward.
