What is Pseudotime trajectory?
The “pseudotime” is defined as the positioning of cells along the trajectory that quantifies the relative activity or progression of the underlying biological process.
What is a trajectory analysis?
Overview. A trajectory describes the course of a measured variable over age or time. Investigators in epidemiology and other fields are often interested not only in the trajectory of variables over time, but also in how covariates may affect their shape.
What is monocle3?
An analysis toolkit for single-cell RNA-seq.
What is diffusion Pseudotime?
DPT (Diffusion pseudotime) is a tool to estimate the temporal order of differentiating cell in single-cell RNA-seq (scRNA-seq) data. The DPT algorithm using diffusion-like random walks to estimate transitions between cells.
What is trajectory interference?
Trajectory inference or pseudotemporal ordering is a computational technique used in single-cell transcriptomics to determine the pattern of a dynamic process experienced by cells and then arrange cells based on their progression through the process.
What is cell Pseudotime?
Pseudotime is a latent (unobserved) dimension which measures the cells’ progress through the transition. Pseudotime is related to but not necessarily the same as laboratory capture time.
What is group trajectory?
Trajectory groups are latent strata; that is, they are groups of individuals following approximately the same developmental course. Individuals do not actually belong to trajectory groups; rather, they are assigned a probability of group membership.
What is latent trajectory?
Traditionally called latent growth curve models, latent trajectory models (LTM) are a relatively new technique to model changes of a certain phenomenon over time.
What is Pseudotime monocle?
Monocle introduced the concept of pseudotime, which is a measure of how far a cell has moved through biological progress.
How do you install a monocle?
To install, open terminal and type xcode-select –install and then follow the prompts. When it has completed installation, restart the Monocle 3 installation instructions.
What is a Pseudotime analysis?
The objective of pseudotime analysis is to take a collection of high-dimensional molecular data from a cross-sectional cohort of individuals and to map these on to a series of one-dimensional quantities, called pseudotimes.
How does single cell sequencing work?
The sequencing step generates thousands of sequencing reads for each individual cell. This raw sequencing data is then mapped to the corresponding reference transcriptome, and Quality Control metrics are generated for each sample. Finally, the data is ready to be analyzed.
