 This module shows a map of temporal trajectories for a selected measure over time. Each patient is represented by a small line, and the lines are ordered in a left-to-right, top-bottom manner. The measures shown over time are defined by the authors of the study shared in this portal.

 ### Compare trajectories of groups

 This module displays scatterplots with the expression of a selected gene and a selected observed measure over time. Each scatterplot contains a subset of samples/patients that is defined by the study authors. This module is useful to see how expression changes over time relative to a measure such as disease activity.

 ### Gene projection overlay

 This module displays two scatterplots of a precomputed 2D projection of genes. The objective of the module is to allow the exploration of the relationship between the genes using a dimensionality reduction method and an expression overlay. In the overlay, the color of each projected gene is the average expression of the samples selected on the sidebar.
