trajectory 
The trajectory as created by 
dimred 
The dimensionality reduction of the cells. A matrix with the positions of cells (rows) in the dimensions (columns) 
waypoints 
A set of waypoints, which can be created by

trajectory_projection_sd 
The standard deviation of the gaussian kernel 
A list containing
dimred_segment_points: The dimensionality reduction of a set of points along the trajectory. A matrix with the position of points (rows) in the dimensions (columns)
dimred_segment_progressions The progressions of the points. A dataframe containing the from and to milestones, and their progression. Has the same number of rows as dimred_segment_points
dimred_milestones: The dimensionality reduction of the milestones. A matrix with the position of milestones (rows) in the dimensions (columns)
These objects can be given to add_dimred()
