Hello,
Thank you for having invovled me in this mailing list :)
I am trying to measure gene expression differences using RNAseq data.
I
did several runs using the package R/DESeq. For my testing data I used
a
*.cvs file, i.e. a table of raw counts containing more than 10800000
reads with 2 conditions (no replicate)
I get the following error message after calling the function "cds
<-estimateDispersions(cds, method='blind',sharingMode='fit-only',
fitType='local')":
----------------------------------------------------------------------
----------------------------------------------------------------
/Error in lfproc(x, y, weights = weights, cens = cens, base = base,
geth
= geth, :
newsplit: out of vertex space
In addition: There were 50 or more warnings (use warnings() to see the
first 50) /
----------------------------------------------------------------------
-----------------------------------------------
I've read that this error is related to maxk parameter value in
locfit,
so I increased it from 300 to 11000000. But the provided solutions did
not work.
Would you please help me to find out what wrong with my test?
Thank you very much and kind regards,
Im?ne

I have similar error messages with a recently installed DESeq2, that I run from python via r2py:
To make this even more complicated, this is run from snakemake, with which I regularly experience memory-related problems when I run too many processes in parallel. The "out of vertex space" message let me suspect that my problem was something similar, but the error persists even when running only one process. I will have to run the analysis "manually" from R to further reduce the potential sources of problems.
I confirm that the problem occurs when running the analysis manually:

specify fitType='local' or 'mean' to avoid this message next time.
