bwgs.cv：Error in geno_impute[1:5, 1:20] : subscript out of bounds

[Long-zhe]

Dear author, hello. Thank you very much for developing the BWGS package, which allows me, as a rookie, to easily conduct research related to genome selection breeding.When I use the bwgs.cv function in the BWGS package, the following error occurs:

I guess it's because the number of SNPs is too small, so the program can't calculate properly? Because when I increase the number of SNPs (after trying many times, the program can run successfully after about 25 SNPs). The program can run normally. Could you please help me check what caused this situation during your free time? Thank you.
