Gemma linear mixed model analysis with second grm format

Question

[dp0b]

Hi

I have been trying to run a univariate linear mixed model using GEMMA. However I was hoping to use a grm I have made else where- it is the second in grm format. The first few lines are as as follows

1       1       8.923316e-01
1       2       -5.544370e-02
1       3       1.903249e-02
1       4       1.880089e-02
1       5       9.801378e-02
1       6       -3.117359e-02
1       7       2.540684e-01
1       8       -1.174230e-01
1       9       1.168132e-01
1       10      1.833550e-01

Then I am trying to run a lmm using the follow command

./gemma.linux -bfile mouse_hs1940 -km 2 -k mouse_plinkgctasorted.txt -lmm 2 -o mouse_plinkgctasorted

However I keep getting the following error. Any advice on how to fix this?

Reading Files ...
## number of total individuals = 1940
## number of analyzed individuals = 1410
## number of covariates = 1
## number of phenotypes = 1
## number of total SNPs = 12226
## number of analyzed SNPs = 10768

gsl: newton.c:74: ERROR: derivative is zero
Default GSL error handler invoked.

The file will run the analysis when I supply a gemma grm, however the file I intend on supplying will be much larger and would prefer to make the grm elsewhere.

did you end up figuring out what caused this error on yours?
