12AD50320_MAXGT 12AD50320_POLY are the name of the samples, this is was set by your upstream command(s).

Please choose a more descriptive title and tag

[Pierre Lindenbaum]

of course you have a problem. Please, change the title.

[Pierre Lindenbaum]

while it works, it's safer to use bcftools view -G in.vcf -o output_file.vcf

thanks for your response sir @Pierre Lindenbaum

bcftools view -G in.vcf -o output_file.vcf

this command I'm used MAXGT AND POLY column removed but how to going GWAS study without sample column information like genotype(GT) and genotype Quality(GQ)information.

This is output result sir

#CHROM  POS ID  REF ALT QUAL    FILTER  INFO
chr16   60054   rs62028702  A   C   23  PASS    DP=9
chr16   60087   rs62028703  C   G   27  PASS    DP=13
chr16   60095   rs62028704  G   T   26  PASS    DP=13
chr16   60120   .   G   A   11  q20 DP=10

Please solve this sir

Your question is not so descriptive but based on the hint of GWAS i think you might want to remove both columns completly.

SO, if you want to remove whole columns 12AD50320_MAXGT and 12AD50320_POLY assuming you are using linux terminal then use

cut -f 1-9 input_file.vcf > output_file.vcf

No. From the question, it's obvious the user is not bioinformatics savvy. Don't give them unsafe commands. Use well tested tools like bcftools as Pierre recommends.
