## Load dataset from Schlitzer et al., 2015
data("ginhoux")

## Reduce dimensionality and infer trajectory with SCORPIUS
space <- reduce_dimensionality(ginhoux$expression, "spearman")
traj <- infer_trajectory(space)

## Visualise
draw_trajectory_plot(
  space,
  path = traj$path,
  progression_group = ginhoux$sample_info$group_name
)
