I am interested nowadays in microarrays, RNA-Seq and genome annotation, GO and pathways. But my goal are to maximize the useful information of each existing experiment. Now I am committing with Bioconductor, you can follow some of my thought in my blog, or in twitter.

Comment: C: WGCNA with "interlinked" experimental conditions as traits
... I haven't work with LC-MS data or tools so I can't recommend a package for this kind of data, but that one you linked seems a good one. Search the literature and papers that cite it to see if it fits your purpose (after you have read the methodology of the tool). However it is different to test di ...

Comment: C: WGCNA with "interlinked" experimental conditions as traits
... In some context it seems that it should be enough to find some pattern that is common between conditions. If you want to find soft relationships between genes you need to have highly similar samples and that depends on the effect size of the changes of each condition, but with so many different cond ...

Answer: A: WGCNA with "interlinked" experimental conditions as traits
... You seem to have very low number of samples per conditions which makes this type of analysis unsuitable for you (if there are high differences by condition), It is recommended to use at least 20 samples for analysis which would mean mixing different conditions, thus making the groups of genes correl ...

Comment: C: Why GSVA returns a matrix with fewer gene-sets?
... And which type of list is it: one with genes: pathways or pathways genes? Load it as a GeneSetCollection and post here the output of printing it. I think that there are some gene sets with empty genes, or could be that the genes are not mapped to your matrix of probes/genes per sample ...

Comment: C: Why GSVA returns a matrix with fewer gene-sets?
... Ok, are you sure you are using 186 Gene sets?? It seems like it is subseting by genes and not gene sets (subseting by number in a GeneSetCollection produces this, while subseting by name subsets by GeneSet name) or something alike. Where does the loadGSC function come from? Which class is the GSC.C2 ...
