Hi,

I am trying to generate my modules using blockwiseModules, with the following code:

net <- blockwiseModules(data_TRAP, power = 8,
                       TOMType = "unsigned", minModuleSize = 30,
                       reassignThreshold = 0, mergeCutHeight = 0.25,
                       numericLabels = TRUE, pamRespectsDendro = FALSE,
                       saveTOMs = TRUE,
                       saveTOMFileBase = "GADD34_BDNF_TOM",
                       maxBlockSize = 15000,
                       deepSplit = 2.5,
                       verbose = 3)


sessionInfo( )

The process runs smoothly, until it gets to the end, when this warning comes up:

Error in (new("standardGeneric", .Data = function (x, y = NULL, use = "everything",  :

My object is then not generated, and TOM block is not saved. Would anyone know the problem? Thanks.

WGCNA is not a Bioconductor package, you're not at the right spot here. However, googling the last line of your error (always recommended to do that) points to various reports including https://www.biostars.org/p/305714/ suggesting namespace issues.
