How to get GFF file in genome guided assembly using StringTie

Question

[Bioinfonext]

For genome guide assembly, I used the below command:

/home/yog/software/stringtie-1.3.2.Linux_x86_64/stringtie -p 8 -G gene.gtf -o genome.gtf -m 500 -v mapped.sorted.bam

genome gtf file generated, please suggest how I can get gff file also.

Thanks
