Hi, I'm using isoRelate to generate IBd matrix but it gave an error message "Error: cannot allocate vector of size 317.9 Gb" this error is coming from this function call my_matrix <- getIBDmatrix(ped.genotypes =Afropop_new_chr,ibd.segments = Afropop_new_ibd_chr)

I suspect it has to do with the RAM. I'm thinking of incorporating ff package to resolve this issue. Any advice on how to implement this or how to resolve this issue

regards Archie
