how to create a gene co-expression network?

I have stagewise file of genes(early stage)-

genename|EntrezGene|Startposition|Endposition|RefAllele|TumorSeqAllele|TumorSeqAllele2|sample   
    ABAT      18         8873373     8873373         G        G             A         TCGA- 6961

i have also file of expression data-

entrez_Id   TCGA-6433   TCGA-6961   TCGA-4075   TCGA-4076
    ABAT     1228         8086         2950      1613

    ABCA1    1254         8115         5510      2015
    ABCA2    270          776          355       553

you need to have a gene expression matrix and you can create co-expression network using WGCNA. https://horvath.genetics.ucla.edu/html/CoexpressionNetwork/Rpackages/WGCNA/
