Difficulties getting **the adjacency file** necessary for **aracne2regulon** function.

Question

[Biostars2200]

Hello, I've newly started learning bioinformatics.

I wonder how to infer regulons from an expression matrix (row=genes, columns=samples) in R studio.

I have difficulties understanding the adjacency file necessary for aracne2regulon function.

How can I get the adjacency file?

Kindly ask some advice.

Thank you.
