Error: long vectors (argument 1) are not supported in .Fortran
Just to set the record straight, WGCNA is a CRAN package. As to Ankush's question - the current WGCNA version does not support analysis of more than about 46300 nodes (probes) in one block. You have two options: 1. filter out some of the least-informative probes (e.g., probes with lowest mean expression or lowest variance); 2. use the "blockwise" approach as implemented in blockwiseModules. Set the maxBlockSize argument to say 40000, and the function will automatically split your data into 2 blocks and run the analysis in each block separately. The third option is to wait a few weeks (possibly months), I do have a WGCNA update in the works that __should__ work on blocks larger than 46300. Best, Peter

Probably wrong list. Try the Bioconductor list instead.

Hi all , I'm working on WGCNA on R-3.3.1 version to reconstruct gene -gene coexpression networks of 54000 probes in 230 samples on Load Sharing facility (Remote computing cluster). Despite memory at dispose, I'm encountering a error of allocation of memory at soft thresholding step or at TOM Similarity step. The problem of memory allocation at soft thresholding step was corrected by allocating the required memory using [bsub -R "rusage[mem=40000]". Error Message
> # Turn adjacency into topological overlap
TOM = TOMsimilarity(adjacency);
Error in TOMsimilarity(adjacency) :
long vectors (argument 1) are not supported in .Fortran
Calls: TOMsimilarity -> .C
Execution halted
Warning message:
system call failed: Cannot allocate memory
Is there a way to run build this TOMsimilarity matrix.
Thanks
