@knausb I can not find your email address. Hence, I attached my test data(unpublished) here. Once you download it I will delete it. |

Hi @lihe-s , apologies for the slow response! R 4.0.0 was released, dplyr 1.0.0 is getting ready for release. And there's this COVID-19 thing. And I just accepted a new job. So things have been a bit busy. Here's what I see. library(vcfR)

But I am saying that I do not feel that I'm reproducing your reported behaviour. Usually we ask folks to upgrade to the latest versions of all software. The release of R 4.0.0 (2020-04-24) may come with some "growing pains", so I wouldn't recomend that. But I think you should check that you have similar versions to what I'm running with the hope that this will reproduce the behaviour I'm seeing on my end. And I'm going to add that I'm preparing a new release of vcfR to address the release of dplyr 1.0.0. So everything is changing, apologies. Thanks! |

@knausb Congratulations on your new job. Thanks a lot for your detailed issue description. So the new version of vcfR will compatible my situation? |

Hi @lihe-s , I don't think you understand. I have failed to reproduce the behavior that you have reported. This means I can't address your issue. I suspect the issue is that you are using an outdated version of adegenet. In the above output I show that I'm using While my results look closer to success than your reported behavior, I don't think we have a solution. The results from |

@knausb Thanks for your reply. I have to say your results are similar to mine. It is true that "variant chr01_1339 has the genotype "0/0/0/0/0/0" and variant chr01_1405 has the genotype NA". If you check |

It looks like the vcfR2genlight can not convert polyploid samples. This is not a rare issue #128 #117 (also a recent paper https://doi.org/10.1038/s41559-019-0807-4). Please consider to help me figure it out. Thanks.
Sorry for the irregular format.
My real world test data will send to you.
