Background:

Single-cell RNA sequencing (scRNA-seq) and spatially resolved transcriptomics (SRT) are vital for life science advancements.
Data simulation is crucial for developing and benchmarking bioinformatics tools for scRNA-seq and SRT.
Existing simulation methods lack comprehensive performance assessments, hindering optimal tool selection.

Purpose of the Study:

To systematically evaluate the performance of simulation methods for scRNA-seq and SRT data.
To provide practical guidelines for selecting appropriate simulation tools.
To identify potential compatibility of scRNA-seq methods for SRT data simulation.

Main Methods:

Evaluated 49 simulation methods using 152 reference datasets from 24 platforms.
Assessed methods based on accuracy, functionality, scalability, and usability.
Analyzed execution errors and parameter estimation issues.

Main Results:

SRTsim, scDesign3, ZINB-WaVE, and scDesign2 showed top accuracy across platforms.
Some scRNA-seq methods demonstrated compatibility for SRT data simulation.
Phenopath, Lun, Simple, and MFA offered high scalability but lacked realistic data generation.
Execution errors often stemmed from parameter estimation failures.

Conclusions:

No single simulation method is superior across all criteria.
Users must balance method accuracy with scalability and functionality.
Developed practical guidelines, a pipeline (Simpipe), and an online tool (Simsite) to aid method selection and data simulation.
