varianceStabilizingTransformation and input data about pywgcna HOT 3 CLOSED

Hi,

Thank you for your interest :)

quote from our paper:
We recommend prior preprocessing and normalization of input gene or transcript expression data, including any necessary batch correction.

The data in the tutorial is the TPM matrix and within the package, we usually would like to remove any low-expressed genes across all samples, and TPMcutoff is the threshold to define low-expressed genes however it's up to the user to decide which input would work best so, in summary, you can pass any form of gene expression data as an input (csv, tsv or AnnData) and if you wish to not remove any low expressed genes you can put TPMcutoff to zero

from pywgcna.

Ok, thanks. So beyond TPMcutoff there is no assumptions of data being TPM and I can pass anything so long I set TPMcutoff=0. Did I understand correctly?

The only assumption is that you pass an expression data.
TPMcutoff can also considered as an expression cutoff and you can assign any value that suits your data
