I have some different types of data (real data, semisynthetic data, and fully synthetic data generated using splatter software). When running the data and got the message "every gene has at least one zero. vst transformation is NOT feasible”, the running process is successful. However, when running different data and got the message "vst transformation is feasible" the execution failed (running process failed). The error message is

  1. "Error in vst(Zkg.tum.round, nsub = min(nrow(Zkg.tum.round)/5, 1000)) :
    less than 'nsub' rows with mean normalized count > 5,
    it is recommended to use varianceStabilizingTransformation directly".

I check the file called runTed.R and this command is in line 335. The suggestion there said that,

  1. #adjust nsub, to avoid error when too few genes are used
    What I understand that I need to change the function vst() on the line 335 to varianceStabilizingTransformation(), but it does not work either. Also, I have no idea how to adjust nsub (the suggestion number 2 above).

Could you please give a suggestion? Thank you.

I attach the two sample data types.
