I am new to PLINK and I am having trouble using one of the commands. I am trying to perform logistic regression analysis on several Ped and map files. Here is the command I put in:
plink --file TWBR10907-07_TWB2_QC --logistic --covar TWB2.0_2.6_3.txt --covar-name SEX,PARKISON --out logistic_results TWB2.0_2.6_3.txt: FID IID SEX PARKISON TV2N_20203805G TV2N_20203805G 1 0 TV23_20182701G TV23_20182701G 1 0 TV29_20181602E TV29_20181602E 1 0 TV23_20182809B TV23_20182809B 2 0 TV23_20180107G TV23_20180107G 2 0 TV2N_20203806G TV2N_20203806G 2 0 TV23_20180108G TV23_20180108G 1 0 TV29_20181603F TV29_20181603F 1 0 TV21_20180301B TV21_20180301B 1 0 TV2A_20190103E TV2A_20190103E 2 0 TV29_20181605E TV29_20181605E 2 0 TV23_20180105C TV23_20180105C 2 0 TV2A_20190103D TV2A_20190103D 2 0 TV2A_20190108G TV2A_20190108G 2 0 TV2A_20190103G TV2A_20190103G 2 0 TV2A_20190104D TV2A_20190104D 1 0 TV2A_20190104A TV2A_20190104A 2 0
I get back the following message and error:

I've searched online and I can't find anything on this error. Can anyone please help me out?
