Pre-computed pilot data from THP-1 monocytic leukemia cells generated using 10x Chromium technology. Contains baseline gene expression parameters and library size information for power analysis of CRISPR-based perturbation experiments.

Usage

THP1_Yao

Format

A list with 3 elements:

baseline_expression_stats

Data frame with gene expression data (16,366 genes × 3 columns):

  • response_id: Character vector of Ensembl gene IDs

  • relative_expression: Numeric vector of relative expression levels (TPM/1e6 scale)

  • expression_size: Numeric vector of dispersion parameters (theta)

library_parameters

List containing saturation curve parameters estimated using preseqR. Data-adaptively selected method: ZTNB. Contains:

  • method_used: "ZTNB" - Zero-truncated negative binomial method

  • L: 4.96e8 - Total expected distinct UMIs at saturation

  • size: 1.79 - ZTNB shape parameter

  • mu: 0.124 - ZTNB mean parameter

  • reads_norm: 10,930 - Normalization constant (reads per cell)

  • n_cells: 5,608 - Number of cells in pilot data

  • UMI_per_cell_at_saturation: 88,390 - Maximum UMI per cell at infinite sequencing depth

mapping_efficiency

Numeric. Mapping efficiency value (0.677)
