Hey, I am using annovar software to annotate my variants, it works well. HOwever, when I converted annotated variant file into txt file, some of the information have missed for no reason as follows,
1) Annotation of variant file
 $ annotate_variation.pl --buildver mm10 mysnps.annovar mm10db/
OUTPUT FILE

2) Convert annotated file to txt file
$ table_annovar.pl -buildver mm10 64snps.annovar.exonic_variant_function mm10db/ -protocol refGene -operation g -nastring NA
OUTPUT file (You can see easily that the orders of the each item are not corresponding to the first line as chr start end ref ....AAchange.reference, and the start/end chromosome position have missed for some reason)
Chr    Start    End    Ref    Alt    Func.refGene    Gene.refGene    ExonicFunc.refGene    AAChange.refGene
