Parsing input file '' failed in function AnalyzeBimbamGXE

[MaxiEstravis]

Hi all, thanks for the great work in GEMMA.
I'm trying to do an analysis with a bim genotype file, a phenotype file, and a GxE file. This is the Linux command line:

~/tools/GEMMA/bin/gemma -g test.bim -p test_pheno.txt -n 1 -a test.anno -k ./output/test_matrix.cXX.txt -gxe test_2021_bio1.data -lmm 4 -o test_BranchQuality_2021_bio1_lmm

This gives the following log with an error:

**** FAILED: Parsing input file '' failed in function AnalyzeBimbamGXE in src/lmm.cpp at line 2329

Because of this error, I suspect that something is wrong with the GxE file, which looks like this:

3.3
4.1
2.9

According to the manual specification (Page 21):

This gxe file contains a column of environmental variables

Besides, this following line without invoking the GxE file works perfectly:

~/tools/GEMMA/bin/gemma -g test.bim -p test_pheno.txt -n 1 -a test.anno -k ./output/test_matrix.cXX.txt -lmm 4 -o test_BranchQuality_2021_bio1_lmm

I noticed there's a related issue that's planning to be incorporated in the new release (Issue #241), but does this mean that I can't incorporate GxE in my analysis for now? Or did I do something wrong?

Cheers,
Maximiliano.
