Hello, I had recently downloaded transcriptome data sets from GEO archive. I am trying to compare them to custom experimental datasets to find overlapping genes and differentially expressed genes. I previously tried using the supplementary files, the .soft files, the GEOquery package to access the transcriptome data, but none seem to have the data. I found that the .csv files had the names of all the genes and their corresponding expression levels for 0-22 days (neuroectodermal differentiation). I was not sure how to use the .csv file to compare the expression data in R. Thanks in advance.
