pairwise is killed

[emgiles]

Hi
I have generated .locs and .sites files from a phased vcf. The convert program runs properly and gives me the summary statistics. When I try to use the .locs and .sites files with pairwise, the program runs and then is "killed" only creating the freqs file. I have approximately 3 million segregating sites and 124 individuals. Any advice would be really appreciated!

Thanks
Emily
