Running a multivariate model with gemma 0.98.4:
gemma -bfile $DATAWORK/genot -k $DATAWORK/K_Plim.txt -lmm 4 -n 12 41 -o mlmm_2traits
I get this wellknown error:
GSL ERROR: matrix is singular in lu.c at line 147 errno 1
But I do not get it using only one trait. So there is no issue with the data files.
I have 100 individuals and 98031 SNPs analyzed.
Traits have a normal distribution and are not correlated as suggested in other issues.
Here is the output :
Do you have any idea to solve this problem ?
Thank you in advance for your help.
