Building Annovar database through gtf file

Question

[humaira.amin96]

I'm trying t build an annovar database through gtf file of Bubalus bubalis using gtfToGenePred. it gives an error message saying "no exons defined for group, feature gene (perhaps try -ignoreGroupsWithoutExons). when use the database built by implement the mentioned parameter, then the annotation results in only intergenic variants and no exonic variants are detected.

Please help me solve this problem.

Thanx.
