class omicverse.bulk.pyGSEA(gene_rnk, pathways_dict, processes=1, permutation_num=1000, outdir='./enrichr_gsea', cutoff=0.5, organism='Human', backend='numpy', weight=1.0, min_size=15, max_size=500, progress=True)[源代码]#

Gene Set Enrichment Analysis (GSEA) wrapper for ranked gene lists.

参数:

  • gene_rnk (pd.DataFrame) – Ranked gene table used for enrichment scoring.

  • pathways_dict (dict|str) – Gene sets — a prepared dict, a .gmt/.txt path, or an Enrichr library name (resolved and auto-downloaded internally).

  • processes (int, optional, default=8) – Number of worker processes.

  • permutation_num (int, optional, default=100) – Number of permutations for enrichment significance.

  • outdir (str, optional, default='./enrichr_gsea') – Output directory for reports and plots.

  • cutoff (float, optional, default=0.5) – Significance/score threshold for result filtering.

返回:

Initializes GSEA analysis settings.

返回类型:

None

示例

>>> # Initialize GSEA object
__init__(gene_rnk, pathways_dict, processes=1, permutation_num=1000, outdir='./enrichr_gsea', cutoff=0.5, organism='Human', backend='numpy', weight=1.0, min_size=15, max_size=500, progress=True)[源代码]#

Initialize pyGSEA with ranked genes and pathway libraries.

参数:

  • gene_rnk (pandas.DataFrame) – Ranked gene table equivalent to GSEA .rnk input.

  • pathways_dict (dict) – Dictionary of pathway collections/gene sets.

  • processes (int, optional) – Number of parallel worker processes.

  • permutation_num (int, optional) – Number of permutations for null distribution estimation.

  • outdir (str, optional) – Output directory for GSEA artifacts.

  • cutoff (float, optional) – Internal GSEA cutoff threshold.

Methods

__init__(gene_rnk, pathways_dict[, ...])

plot_enrichment([num, node_size, cax_loc, ...])

Plot top GSEA terms as bubble enrichment chart.

plot_gsea([term_num, gene_set_title, ...])

Plot running-enrichment curve for one selected GSEA term.
