I''m quite new in bioinformatics world and started working with GEO dataset GSE42023. Our goals is to extract deferentially expressed genes . My question is:

The gse42023 provides me 2 types of files : RAW.tar
and non-normalized.txt.gz.
I know that : i need normalize this data to proceed with dea analisis, but i am really confused with this data.

Specially in non-normalized.txt , i have the genes (rows) , and the samples and p-value detection(collumns),
in this case, how to proceed ?

Thanks!
Example of non_normalized.txt
