Running plink --logistic with SNP x covariate interaction with only a single covariate

Question

[f-rasmussen]

I am running a SNP x covariate interaction, but I have many covariates included in my model only one of which I am interested in as an SNP x Cov interaction. How do I specify which covariate to include in the interaction term, while still keeping the remaining covariates as main effects in the model?

You can try to use the "--parameters" command to specify the interaction test you want, which was taught in the above webpage (the "Linear and logistic models" section, the "Flexibly specifying the model" part)
