Hi, there--
I have a SNPbin object with ~500 individuals genotyped at ~670,000 SNPs. I selected an optimum number of PCs to retain for DAPC using the xval function run in parallel, which took about 3 days on our server. However, as far as I can tell, there's no parallel option for the find.clusters or dapc functions. We've been running the find.clusters function on this dataset using the optimum number of PCs from xval for ~ 2 weeks with no end in sight... Is there a way to parallel-ize find.clusters and dapc? Are there plans to add this functionality to the functions themselves?
I understand that we could randomly subset markers and run DAPC, but in an ideal world, I'd like to be able to compare patterns and inferences across the full dataset and a subset dataset. The code we ran for find.clusters is below.
Thank you!
Audrey
