Cell’s favorite enrichment and analysis tools for differential genes go and KEGG
For transcriptome analysis, after the completion of differential gene screening, it is more than half of the success. Next, the downstream analysis can be carried out. First of all, the most common is the enrichment analysis of up and down regulated genes. We have published an R language version before: Cluster Profiler: a surprise work […]

Enrichment analysis principle and clusterprofiler package for go and KEGG enrichment analysis are described in detail
Concept: Gene enrichment analysisIt refers to clustering analysis of genes according to genome annotation information (go, KEGG) for a given group of genes,That is, whether a given gene is a function in go (or a pathway in KEGG). The purpose of gene functional enrichment is to explain which functions are affected by a given gene […]

Pandas merge CSV files
Scenario: It is troublesome to deliver multiple CSV files in the project. Use pans Merge into a CSV file code: The code is as follows #-*-coding:utf-8-*- import pandas as pd import numpy as np #Read CSV file a = pd.read_table(“a.csv”,sep=”\s+”) b = pd.read_table(“b.csv”,sep=’\s+’) c = pd.read_table(‘c.csv’,sep=’\s+’) d = pd.read_table(“d.csv”,sep=’\s+’) e = pd.read_table(“e.csv”,sep=’\s+’) f = pd.read_table(“f.csv”,sep=’\s+’) […]
