WebA General Feature Format (GFF) file is a simple tab-delimited text file for describing genomic features. There are several slightly but significantly different GFF file formats. IGV supports the GFF2, GFF3 and GTF file formats. GFF2 files must have a .gff file extension for IGV.

WebA SEG file (segmented data; .seg or .cbs) is a tab-delimited text file that lists loci and associated numeric values. The first row contains column headings and each subsequent row contains a locus and an associated numeric value. IGV ignores the column headings. It reads the first four columns as track name, chromosome, start location, and end ... WebApr 5, 2024 · 3.

WebAn IGV file (.igv) is a tab-delimited text file that defines tracks. The first row contains column headings for chromosome, start location, end location, and feature followed by the name of each track defined in the .igv file.
