I have a gff file that contains all the information from Chromosome 1 - Chromosome 14. But I need gff information on individual chromosome basis. For example, I am performing some experiment on Chromosome 11 and trying to visualize my result on IGV. When I load the gff file in IGV it is showing gene information of all the chromosome. How can I get the gff of only Chromosome 11?
Assuming your chromosomes are named `chrNN` the following should extract `chr11`

    grep chr11 your_file.gff > chr11.gff

If chr11 is in the first column and you want only those lines then do

    grep ^chr11 your_file.gff > chr11.gff
