Hello, I am using macs2 for peak calling , on ChIPseq data using the following command. I have done the normalization using the drosophila genome on my data.

macs2 callpeak -t /Normalized_samples_ip/_IP_unique_rmdup_sampled.bam \ -c _001_unique_rmdup_sampled.bam -f BAM --gsize 3.0e9 --broad --broad-cutoff 0.1 --nomodel --extsize 125 --bdg -n peak_call --outdir outputfolder but the result is generating 0 byte gapped and broad peaks file , is it ok ? or what am i doing wrong

any suggestion?? these are the files generated in my result folder
