Z-score difference between Z group means 0 Hello all, a question. In a tutorial on differential expression analysis the following happened: Normalized data was converted to Z-scores and divided into two biological groups. A t-test was performed on the two groups (which is fine). Now the point of confusion. The…

Issues marking genes in ComplexHeatmap

Hi, I was working on marking genes of interest on the heatmap via ComplexHeatmap R package. Instead of specifying row numbers in anno_mark function, I specified a vector of genes to mark on the heatmap (see below) and used a combination of which() and %in% to isolate the row indices…

Answer: using Firebrowser to identify disease type

The solution to this is within the `Samples.mRNASeq` that gives data which can be saved in JSON format: [0] { cohort “ACC”, expression_log2 3.635731, gene “CD274”, geneID 29126, protocol “RSEM”, sample_type “TP”, tcga_participant_barcode “TCGA-PK-A5HB”, z-score -0.01802174 }, [1] { cohort “ACC”, expression_log2 2.725785, gene “CD274”, geneID 29126, protocol “RSEM”, sample_type…

Cross-platform normalization enables machine learning model training on microarray and RNA-seq data simultaneously

We aimed to assess the extent to which it was possible to effectively normalize and combine microarray and RNA-seq data with existing methods for use as a training set for machine learning applications. We assessed performance on holdout sets composed entirely of microarray data and entirely of RNA-seq data. To…

Gene expression normalization sample-wise or feature-wise? which one is the recommended way?

Dear Biostars users, I would like to ask question about z-score normalization (standardization) on gene-expression data.As you can aware from the title, I would like to ask which one is the good way to normalize gene expression data? If I check examples for gene-expression data on the internet usually people…

In vivo transomic analyses of glucose-responsive metabolism in skeletal muscle reveal core differences between the healthy and obese states

Animals and sample preparation Animal experiments were performed as previously described12. C57BL/6J WT mice or ob/ob mice at ten weeks of age were purchased from Japan SLC Inc. (Shizuoka, Japan). The phenotypic data of the mice are summarized in Table S1. Animal experiments were approved by the animal ethics committee…

Nitrogen cycling and microbial cooperation in the terrestrial subsurface

Distribution of nitrogen-cycling pathways in groundwater Differences in nitrogen-cycling processes based on oxygen and nitrate concentrations Sixteen metagenomes (Table S4) were obtained from duplicate wells at four sites (A–D) from two unconfined alluvial aquifers (Canterbury, Fig. S1). These sites encompassed varied nitrate (0.45–12.6 g/m3), DO (0.37–7.5 mg/L), and dissolved organic carbon (DOC) (0–26 g/m3)…

Which is the best type of data for correlation or survival analysis

Hi ATpoint, thanks for your reply and show me the thread. But there are still some questions: (1) dds <- estimateSizeFactors(dds); ntd <- normTransform(dds) would be suggested instead of vst transformation because of elapsed time. May I ask whether the two method could be substituted with each other for correlation…

Single-cell analyses define a continuum of cell state and composition changes in the malignant transformation of polyps to colorectal cancer

Mapping molecular changes across malignant transformation We generated single-cell data for 81 samples collected from eight FAP and seven non-FAP donors (Fig. 1a and Supplementary Tables 1 and 2). For each tissue, we performed matched scATAC-seq and snRNA-seq (10x Genomics). We obtained high-quality single-cell chromatin accessibility profiles for 447,829 cells…

Transcriptomic and proteomic profiling of peptidase expression in Fasciola hepatica eggs developing at host’s body temperature

From the bovine liver, we isolated 97 live F. hepatica adults. After overnight cultivation, we recovered approx. 228,000 laid eggs, which we divided in three groups. The first group (T0) was immediately frozen at − 80 °C, while the other two groups (T5 and T10) were incubated for 5 and 10 days at…

r – RNA-Seq Data Heatmap: Is it necessary to do a log2 transformation of RPKM values before doing the Z-score standardisation?

I am making a heatmap using RNA-Seq data in R. The heatmap shows gene expression values (RPKM) in different brain regions. I have the following code: library(tidyverse) library(pheatmap) library(matrixStats) read_csv(“prenatal_heatmap_data.csv”) -> all_data all_data %>% column_to_rownames(“Brain Region”) -> heatmap_data heatmap_data %>% pheatmap() Which generates the following heatmap: I want to do…

AttCRISPR: a spacetime interpretable model for prediction of sgRNA on-target activity | BMC Bioinformatics

Dataset The dataset we used for training, validation and testing is the DeepHF dataset [17]. We extracted 55604, 58617, 56888 sgRNAs with activity (represented by insertion/deletion (indel)) for WT-SpCas9, eSpCas9(1.1) and SpCas9-HF1, respectively, from its source data, and use the same partition method to divide train set and test set….
