Weblimma -- posthoc analysis when design factor has 3 levels 1 mforde84 20 @mforde84-12150 Last seen 5.7 years ago Hi, I'm analysing some microarray and rnaseq data for gene set enrichment analysis. I have three independent sample groups. I'm using GSVA to do the enrichment analysis then using limma to fit a model to the GSVA enrichment scores. Get enrichment scores by gsva () function on both inputs and both gene sets with one cdf kernel to be Poisson and the other one to be Gaussian. Then apply gsva scores to the limma package to fit a linear model by lmFit () function. Then select pathways with adjusted p value smaller than 0.01 to be gene sets that are significant. flat 17 godwin houseWebMar 16, 2024 · Bar plot showing different pathways enriched in C1QC+ macrophage and SPP1+ macrophage in lung cancer scored per cell by gene set variation analysis … flat 1930s women\u0027s shoes

Then I create a list of gene sets according to the ontology "molecular function". WebUsing the 20 DEGs, SVM and random forest classifiers were also generated and showed high diagnostic efficacy, with respective AUCs of 0.997 and 1.00 against the training set. A GSVA score was also established using the top 20 significant DEGs, which showed an AUC of 0.971 in the training set and 0.989 in the test set.

WebYes, GSVA (via Limma) allows you to compare pathways / gene signatures between groups of samples. It will likely not work with 1 Vs. 1 comparisons, though. GSVA by default will expect a Gaussian distribution, so, your data should indeed be logged or Z-scaled. I believe you can change this default parameter, though.
