Package WGCNA version 1.19 loaded.

Important note: It appears that your system supports multi-threading, but it is not enabled within WGCNA in R.

To allow multi-threading within WGCNA with all available cores, use

allowWGCNAThreads()

within R. Use disableWGCNAThreads() to disable threading if necessary.

Alternatively, set the following environment variable on your system:

ALLOW_WGCNA_THREADS=<number_of_processors>

for example

ALL0W_WGCNA_THREADS=2

To set the environment variable in linux bash shell, type

export ALL0W_WGCNA_THREADS=2

before running R. Other operating systems or shells will have a similar command to achieve the same aim.
