Error estimating covariance matrix and individual admixture proportions

Question

[carolina.santiago.t]

Hi, I am trying to perform a PCA with some strains whole-genome NGS data. When i run the command: python pcangsd.py -beagle name.beagle.gz -admix -o name_test -threads 10, I obtain "ValueError: k must be greater than 0." Can someone help me understand what I am doing wrong? Thanks in advance!
