I have a genome with 4.3 GB size. I have run local blast for it. Now I want to fetch the sequence from the genome like from 700000 bps to 800000 bps. I don't have any information regarding chromosome coordinates or chromosome number etc. because it is a non-redundant data. I have tried to make bed file but it is also not working. I am a beginner. Please help me.
Thank you in advance.
