Description

Hello,

I noticed that I am missing some individuals in my eigen vector output file after running smartpca. My total number of individuals is 322 and the file only has information for 300 individuals. Is there some form of filtering that is done by the software that I am not accounting for?
I also checked the .ind file to see if some may have been mis-assigned to a population with a typo but that doesn't seem to be the case. I would greatly appreciate your help.

Research direction

Start by reproducing the smartpca run described in the issue and compare the 322 individuals with the 300 entries in the eigenvector output. Investigate whether smartpca filters individuals despite the reported .ind population assignments; done means explaining the discrepancy or identifying a reproducible software defect.
