snapper about sample size

[Grace0114]

Hello.
I'm a newcomer to phylogenetic research and am now building phylogenetic trees with snp data. Fortunately, I find that software beast has a snapper program to fix my problem. But my sample size is 64 samples, including 17 species. I see it in snapper-delimitation-tutorial.pdf -" The method works well for relatively small numbers of species (minimum = 2; maximum is
probably near 20 due to computational constraints)". Do I build a phylogenetic tree with snapper? If this snapper can't use my data to build trees, is there any other good software to solve the problem of building trees with large samples of SNPS like me? Sorry, I can't sign in to google to ask this question at the BEAST2 google users group.
Looking forward to your reply. Thank you very much.
