Hi all, a user contacted me about a segfault when installing WGCNA package dowloaded from CRAN. I also see a segfault like that on certain installs of R. The package passes all CRAN checks, so presumably this has something to do with the R installation or environment. The R versions here are not

Hi Peter, Thank you for your time and input on this matter. I will take your advice and reconstruct the blocks using a different maximum cutoff and plot the figures next to one another. I also wanted to thank you for creating the WGCNA package and including the section on exporting to other visual

2012-10-18 Thread Peter Langfelder
Hi Derek, the simple answer is that the block-specific dendrograms cannot be meaningfully combined into a single dendrogram. You have to plot them separately. You can create a multi-panel figure that shows all block dendrograms in one big figure, although with 10 blocks I would not necessarily att

Dear Peter, I have another question about WGCNA. I am using the package for meta-analysis to find modules preserved in several datasets. However, I am unsure how to handle the softpower, because each dataset has its own ideal scale indepence value. When combining several datasets what should I do?
