Dear this image resulted from plotting the result of picksoftthreshold function in WGCNA ![scale_free and mean connectivity] I need to ask what is the meaning of the sft result from using picksoftthreshold function in WGCNA as this result is considered as a list contain powerestimate which equal to 18 in my case and fitindices dataframe that contain 7 columns [ power, SFT.R.sq,slope,truncated.R.sq,mean.k.,median.k.,max.k.]. First: I just need to understand this dataframe and how power 18 is decided to be a power of my data. Second: What is the importance of mean connectivity plot ?, has it a role in determination of power ?. Third: what is the difference between networktype and TOMtype in blockwiseModules function?.
Note: that my data is expression of multiomics data contain 153 samples and 924 genes.
