Annovar output no comment column?

Question

[okiedokie1208]

I have run the Annovar to annotate my GWAS results. My input (a list of rsID) was converted to avinput first by:

convert2annovar.pl -format rsid GWAS_rsID.txt -dbsnpfile ../../humandb/hg19_snp138.txt > snplist.avinput

Then I run the command to annotate:

 annotate_variation.pl -filter -out ex1 -build hg19 -dbtype snp138 snplist.avinput ../../humandb

It was running, but my output didn't include the information I need. The comment column didn't tell any functional or annotated gene information. It only outputs the matched rsID. It is odd. Could someone help?
