Similarly, the final blockStart position plus theįinal blockSize value must equal chromEnd. In BED files with block definitions, the first blockStart value must be 0, so that the firstīlock begins at chromStart. Items in this list should correspond to blockCount. All of theīlockStart positions should be calculated relative to chromStart.

blockStarts - A comma-separated list of block starts.

This list should correspond to blockCount.

blockSizes - A comma-separated list of the block sizes.

blockCount - The number of blocks (exons) in the BED line.

ItemRgb attribute is set to "On", this RBG value will determine the displayĬolor of the data contained in this BED line.

itemRgb - An RGB value of the form R,G,B (e.g.

thickEnd - The ending position at which the feature is drawn thickly (for example.

When there is no thick part, thickStart and thickEndĪre usually set to the chromStart position.

thickStart - The starting position at which the feature is drawn thickly (forĮxample, the start codon in gene displays).

The first 100 bases of chromosome 1 are defined as chrom=1, chromStart=0, chromEnd=100,Īnd span the bases numbered 0-99 in our software (not 0-100), but will represent theĬhromStart and chromEnd can be identical, creating a feature of length 0, commonly The number in position format will be represented. TheĬhromEnd base is not included in the display of the feature, however,

chromEnd - The ending position of the feature in the chromosome or scaffold.

The first base in a chromosome is numbered 0.

chromStart - The starting position of the feature in the chromosome or scaffold.

chrom - The name of the chromosome (e.g.

Own server, you should use the bigBed data format. If your data set is BED-like, but it is very large (over 50MB) and you would like to keep it on your

Header lines are not permissible in downstream utilities such as bedToBigBed, which convert lines of Which begin with the word "browser" or "track" to assist the browser in theĭisplay and interpretation of the lines of BED data following the headers. Please note that only in custom tracks can the first lines of the file consist of header lines, Only some variations of BED types, such asīedDetail, require a tab character delimitation for Some circumstances, if the field content is to be empty. The order of the optional fields is binding: lower-numbered fields must alwaysīe populated if higher-numbered fields are used.īED information should not be mixed as explained above (BED3 should not be mixed with BED4), ratherĪdditional column information must be filled for consistency, for example with a "." in The number of fields per line must be consistent throughout any single set of data in anĪnnotation track. BED lines have three required fields and nine additional optionalįields.
