I have files ‘cg.ped’ and ‘cg.map’.
I used plink --file cg --assoc --out data
to get data.assoc
Then I used plink --file cg --model --out data
to get data.model
However, in the data.model there are some missing values, like in lines 601-605 (0 in that A column, but missing values in that G column)
597 0 exm2270713 A G TREND 146/252 120/250 3.104e+00 1 7.811e-02

607 0 exm2277076 A C TREND 2/414 2/380 3.656e-03 1 9.518e-01
For these missing values, it causes that the follow-up work cannot continue.
Why and how to deal with this?
Thank you very much!
