Standardizing gene symbols
... Hello all, I have a list of gene symbols that I obtained after querying CHEMBL and a separate list of gene symbols from querying datasets from GEO and using Limma on them. When I try to compare both lists, I find that I cannot look for similar gene symbols as gene synonyms exist. An example would ...

Volcano Plot (highlighting top genes in a different color)
... Hi everyone, I am trying to plot Volcano plots for analysis mostly from Limma. I found 2 sources- one that labels points above certain thresholds of adjusted p values and logFC values and another one that uses the MarrayLM object as input and labels the top gene hits. Here are the source links: 1 ...

Comment: C: DEG with Limma without replicates and best plots to represent results
... Hi Aaron, Thank you so much, this explains a lot, appreciate the help. Just to clarify, when we make a contrast matrix and in the final output for fit2$coefficients, we get +2 for groupsA-groupsB for Gene A, this would mean that Gene A was down regulated by (lg2) times in groupsB with respect to g ...

DEG with Limma without replicates and best plots to represent results
... Hi all, I have a few questions regarding Limma. 1) I am asking a question with reference to https://support.bioconductor.org/p/48601/#102609. This is a case where there are no replicates for samples, and we cannot run eBayes or toptable. I understand that running fit2$coefficients will bring out l ...
