dataset |
One or more datasets as created by |
method |
One or more methods. Must be one of:
|
parameters |
A set of parameters to be used during trajectory inference.
A parameter set must be a named list of parameters.
If multiple methods were provided in the |
give_priors |
All the priors a method is allowed to receive. Must be a subset of all available priors (priors). |
seed |
A seed to be passed to the TI method. |
verbose |
Whether or not to print information output. |
return_verbose |
Whether to store and return messages printed by the method. |
debug |
Used for debugging containers methods. |
map_fun |
A map function to use when inferring trajectories with multiple datasets or methods. Allows to parallellise the execution in an arbitrary way. |
... |
Any additional parameters given to the method, will be concatenated to the parameters argument |
infer_trajectory
: A trajectory object, which is a list containing
milestone_ids: The names of the milestones, a character vector.
milestone_network: The network between the milestones, a dataframe with the from milestone, to milestone, length of the edge, and whether it is directed.
divergence_regions: The regions between three or more milestones where cells are diverging, a dataframe with the divergence id, the milestone id and whether this milestone is the start of the divergence
milestone_percentages: For each cell its closeness to a particular milestone, a dataframe with the cell id, the milestone id, and its percentage (a number between 0 and 1 where higher values indicate that a cell is close to the milestone).
progressions: For each cell its progression along a particular edge of the milestone_network. Contains the same information as milestone_percentages. A dataframe with cell id, from milestone, to milestone, and its percentage (a number between 0 and 1 where higher values indicate that a cell is close to the 'to' milestone and far from the 'from' milestone).
cell_ids: The names of the cells
Some methods will include additional information in the output, such as
A dimensionality reduction (dimred), the location of the trajectory milestones and edges in this dimensionality reduction (dimred_milestones, dimred_segment_progressions and dimred_segment_points). See add_dimred()
for more information on these objects.
A cell grouping (grouping). See add_grouping()
for more information on this object.
infer_trajectories
: A tibble containing the dataset and method identifiers (dataset_id and method_id), the trajectory model as described above (model), and a summary containing the execution times, output and error if appropriate
dataset <- example_dataset
method <- get_ti_methods(as_tibble = FALSE)[[1]]$fun
