Representation of svp dynamics along the two paths in eye disc differentiation. The gray horizontal line represents the TF expression threshold for arrows to be drawn. For cells below this threshold, the GRN velocity values are set to 0. The gray dashed line represents the penalization curve, which is the GAM fitted curve drawn using the standardized data across all possible paths for the cells in that path. Those points where the penalization and the TF expression curve disagree are considered artifacts (the TF gene seems to be expressed even if there is low expression, due to the standardization of the TF curve in that specific path). The red curve represents the GAM fitted curve using the standardized TF expression data (along the path) and the blue curve represents the GAM fitted curve using the standardized gene enrichment scores (along the path).
