Possible to remove .nosex IDs in Plink1.9

Question

[salman_96]

Hi, In my fam file I have 4 individuals with no sex information. Is it possible to exclude them from downstream analysis. I have tried --allow-no-sex as well as --must-have-sex but they are kept in a .nosex file.

I am testing for interaction analysis in another tool with plink set of files

Thank you All. Appreciate it

Two options:

1. Use --remove on the .nosex file.
2. Download plink 2.0, and use its --remove-nosex flag.
