It seems as if I can't get --max-alleles to be recognized no matter what I do. The command below gets interpreted as requesting snps with at most 2 alleles. Any suggestions? What am I doing wrong?

vcftools --gzvcf combined.vcf.gz --maf 0.05 --max-alleles 3 --max-maf 0.5 --hwe 1e-8 --minQ 40 --012 --max-missing 0.95 --chr chr22 --out combined.chr22.common
