Fraction of forward and backward fluxes being active.

For each potentially bidirectional reaction, it is counted how often the forward and backward flux samples had non-zero values in the MCMC runs. If the value is above 95%/below 5% the direction is assumed to be active (denoted by “+”)/inactive (denoted by “-”), otherwise, the data is inconclusive (denoted by “?”). The principal direction is inferred from 95% net flux credible intervals.
