Single cells, many algorithms. The goal of this page is to catalog the many algorithms that estimate pseudotimes for cells based on their gene expression levels. This problem is also referred to as single-cell trajectory inference or ordering. It contains method names, software links, and manuscript links and simply seeks to list as many methods as possible without commentary. Some related methods not specifically designed for RNA-seq (e.g. mass cytometry) are included as well, as are some methods for estimating RNA velocity. The list also includes methods that are specifically designed to take pseudotemporal data as input.
The initial list was created by Anthony Gitter, but pull requests are very welcome. Thank you to the other contributors.
Anthony Gitter. Single-cell RNA-seq pseudotime estimation algorithms. 2018. doi:10.5281/zenodo.1297422 https://github.com/agitter/single-cell-pseudotime
Informally, the pseudotime estimation problem can be stated as:
- Given: single-cell gene expression measurements for a heterogeneous collection of cells that is transitioning from biological state A to state B
- Return: a quantitative value for each cell that represents its progress in the A to B transition
There are many ways to approach this problem, and major algorithmic steps that are common to most (but not all) methods are:
- Reduce the dimension of the dataset
- Find a smooth progression through the low dimensional data, assuming that cells that are nearby one another in the low dimensional space have similar expression levels because they are at similar points in to A to B process
Dimension reduction sometimes relies on knowledge of important marker genes and sometimes uses the full gene expression matrix. The trajectory through the low dimensional space can be identified using graph algorithms (e.g., minimum spanning tree or shortest path), principal curves, or probabilistic models (e.g., Gaussian process).
Bacher and Kendziorski 2016, Trapnell 2015, Tanay and Regev 2017, Moon et al. 2017, Tritschler et al. 2019, Weiler et al. 2021, Ding et al. 2022, and Pan and Zhang 2023 provide a more comprehensive overview of single-cell RNA-seq and the pseudotime estimation problem. Cannoodt et al. 2016 reviews pseudotime inference algorithms. Pablo Cordero's blog post discusses why it is hard to recover the correct dynamics of a system from single-cell data. For more general lists of methods for single-cell RNA-seq see seandavi/awesome-single-cell and scRNA-tools. The Hemberg lab single-cell RNA-seq course has an overview of five pseudotime algorithms with usage examples. Many modern ideas for pseudotime estimation are descended from Magwene et al. 2003 on reconstructing the order of microarray expression samples.
Single-cell expression data have also inspired new methods for gene regulatory network reconstruction, as reviewed by Fiers et al. 2018 and Todorov et al. 2018. Several of these, such as SINGE, treat pseudotime annotations as time points and extend traditional time series network inference algorithms for single-cell data. BEELINE, SERGIO, and McCalla et al. 2023 benchmark many of these specialized network inference methods.
Some of the distinguishing factors among algorithms include:
- Use of prior knowledge such as capture times (DeLorean) or switch-like marker genes (Ouija)
- Modeling specific types of biological processes such as branching processes in differentiation (multiple methods) or cyclic processes (Oscope)
- Return a single pseudotime or a posterior distribution over pseudotimes for each cell
- Perform additional analyses after inferring pseudotimes such as regulatory network inference or identifying differentially expressed genes over pseudotime
Saelens et al. 2019 performed a comprehensive evaluation of 29 different single-cell trajectory inference methods and discuss the different types of algorithms in more detail. They benchmark both quantitative performance and assess software quality. See their website and GitHub repository as well. Tian et al. 2018 also include trajectory inference algorithms in their single-cell RNA-seq benchmarking study. Escort is a framework to help guide the selection of a suitable trajectory inference algorithm for a dataset.

Abstract
The availability of high throughput single-cell RNA-Sequencing data allows researchers to study the molecular mechanisms that drive the temporal dynamics of cells during differentiation or development. Recent computational methods that build upon single-cell sequencing technology, such as trajectory inference or RNA-velocity estimation, provide a way for researchers to analyze the state of each cell during a continuous dynamic process. However, with the surge of such computational methods, there is still a lack of simulators that can model the cell temporal dynamics, and provide ground truth data to benchmark the computational methods.Hereby we present VeloSim, a simulation software that can simulate the gene-expression kinetics in cells along continuous trajectories. VeloSim is able to take any trajectory structure composed of basic elements including “linear” and “cycle” as input, and outputs unspliced mRNA count matrix, spliced mRNA count matrix, cell pseudo-time and true RNA velocity of the cells. We demonstrate how VeloSim can be used to benchmark trajectory inference and RNA-velocity estimation methods with different amounts of biological and technical variation within the datasets. VeloSim is implemented into an R package available at https://github.com/PeterZZQ/VeloSim.
