Hi! I am using DESeq2 on a RNA-seq data, and when I finally run the DESeq() function, I get a strange error, for which I am not able to get information about anywhere. Please help.

res=DESeq(result, parallel = TRUE)

The first 3 lines of the result are as follows:

estimating size factors
estimating dispersions
gene-wise dispersion estimates: 2 workers

Then, after spending a considerable amount of time (20-30 minutes) in this state, I get the following error:

Error in match(attrnames, specials) : 478 arguments passed to .Internal(match) which requires 4

I am unfortunately not able to understand how to resolve this.

Try turning off parallel.

There is likely a backend and system specific problem you are encountering.

Anyway, I don’t often use parallelization. Filtering genes is often sufficient.
