ComBat_seq took a very long time
Hi, I was using ComBat_seq for RNA seq data, and I have covar_mod as the argument, which has 8 variables, however, it has been run more than 10 hours, and still not completed, which is wired.
I wonder why it took so long?
I have the same issue too, in fact I only have 2 covariates but still for over 15 hours, it is in process. It would be really helpful if you share how long it took..! I'm wondering if I have to execute it or not.. Thanks! @rongwong1119 @DamienTan
I now used two covariates, and it took only a few minutes.

@rongwong1119 Thanks for your quick reply! I'm sure that somethings wrong with my job then... One thing more just in case, I have 1300 samples and 200 genes.. is this matrix size pretty similar to your work? If it is even smaller than your work, I should really abort and check other solutions...!! Thanks again for your quick reply :)

Yep, I used the argument "covar_mod" to add 2 covariates, but it took me more than 4 days and was still running. Finally, I killed this process. Maybe only using the argument "group" can avoid this problem, but there is another problem, which will create some very large values at the adjusted matrix. #20
I have 20000+ genes and 60 samples

Hi all! I faced a similar problem: I have 2 covariates in 'covar_mod' matrix and the analysis has been running for 7 days already. @DamienTan did you manage to solve this problem?
@DamienTan Thanks for the answer. Have you used any other program?
@maxnest Haven't! as I commented above, there were another problem using the argument "group". But I didn't use other program.
