Convert blastn to gff3

Question

[kspata]

Hi I have the output of blastn in a tabular format. I need to convert this into a gff3 format. How to write a parser for this or how can i do it without parser?

Why do you specifically not want a parser?

Hi I am open to use a parser as well.. the question is just how to write it?
