左から順に9列の情報から構成されている。

• seqname - The name of the sequence. Must be a chromosome or scaffold.
• source - The program that generated this feature.（省略可，その代わりにタブを入れる）
• feature - The name of this type of feature. Some examples of standard feature types are "CDS", "start_codon", "stop_codon", and "exon".（省略可，その代わりにタブを入れる）
• start - The starting position of the feature in the sequence. The first base is numbered 1.
• end - The ending position of the feature (inclusive).
• score - A score between 0 and 1000. If the track line useScore attribute is set to 1 for this annotation data set, the score value will determine the level of gray in which this feature is displayed (higher numbers = darker gray). If there is no score value, enter ".".
• strand - Valid entries include '+', '-', or '.' (for don't know/don't care).
• frame - If the feature is a coding exon, frame should be a number between 0-2 that represents the reading frame of the first base. If the feature is not a coding exon, the value should be '.'.
• group - All lines with the same group are linked together into a single item（省略可）
