Hi
I am using raw count data from single cell RNA-seq and bulk RNA-seq. I am currently stuck at running the deconvolution function solveDampenedWLS(). I get the error :
Error in solve.QP(D, d, A, bzero) : matrix D in quadratic function is not positive definite!
I tried to solve this using nearPD() to get the nearest positive definite matrix for the data , but I still get the same error.
Can you suggest a way I can fix this issue?
Thanks a lot!
Hello,
I ran into the same error. Did you find any solution to that? Thanks
Hi, I solved this issue using
solution<-solve.QP(D,d,A,bzero, factorized = TRUE)$solution
instead of
# solution<-solve.QP(D,d,A,bzero)$solution
Best
