Hello, I having the error that has been mentioned before in the rma function of the oligo package. That one

eset <- rma(dat)
Background correcting

I have tried choosing the alternatives to use blas instead of openblas, since I read online that you have to downgrade it or use blas instead, but it doesn't seem to work.

This is what I have selected

sudo update-alternatives --config liblapack.so.3-x86_64-linux-gnu
There are 2 choices for the alternative liblapack.so.3-x86_64-linux-gnu (providing /usr/lib/x86_64-linux-gnu/liblapack.so.3).

But when I open R after it still seems to be pointing to the openblas path I attached in the first session info.

Any idea on how to fix it?

Many thanks!

This likely has to do with an issue of preprocessCore. Disabling its internal threading while installing preprocessCore has been reported to solve the problem in a similar case. Check here on how to do that (the last post): Minfi issue: return code from pthread_create() is 22
