Off topic:Can I get the intergenic regions if I have these files?

Question

[kiomix106]

sorry if I do not know much about this

NC_000001.11    RefSeq  region  1   248956422   .   +   .   ID=NC_000001.11:1..248956422;Dbxref=taxon:9606;Name=1;chromosome=1;gbkey=Src;genome=chromosome;mol_type=genomic DNA

this is a .gff file

and this one is a .out

Can I get the intergenic regions and as in the case that I can? I mostly use awk and bedtools
