18 **What it does**
|
|
19
|
|
20 This tool converts data from BED format to GFF format (scroll down for format description).
|
|
21
|
|
22 --------
|
|
23
|
|
24 **Example**
|
|
25
|
|
26 The following data in BED format::
|
|
27
|
|
28 chr28 346187 388197 BC114771 0 + 346187 388197 0 9 144,81,115,63,155,96,134,105,112, 0,24095,26190,31006,32131,33534,36994,41793,41898,
|
|
29
|
|
30 Will be converted to GFF (**note** that the start coordinate is incremented by 1)::

51 **About formats**
|
|
52
|
|
53 **BED format** Browser Extensible Data format was designed at UCSC for displaying data tracks in the Genome Browser. It has three required fields and several additional optional ones:
|
|
54
|
|
55 The first three BED fields (required) are::
|
|
56
|
|
57 1. chrom - The name of the chromosome (e.g. chr1, chrY_random).
|
|
58 2. chromStart - The starting position in the chromosome. (The first base in a chromosome is numbered 0.)
|
|
59 3. chromEnd - The ending position in the chromosome, plus 1 (i.e., a half-open interval).
|
|
60
|
|
61 The additional BED fields (optional) are::
|
|
62
|
|
63 4. name - The name of the BED line.
|
|
64 5. score - A score between 0 and 1000.
|
|
65 6. strand - Defines the strand - either '+' or '-'.
|
|
66 7. thickStart - The starting position where the feature is drawn thickly at the Genome Browser.
|
|
67 8. thickEnd - The ending position where the feature is drawn thickly at the Genome Browser.
|
|
68 9. reserved - This should always be set to zero.
|
|
69 10. blockCount - The number of blocks (exons) in the BED line.
|
|
70 11. blockSizes - A comma-separated list of the block sizes. The number of items in this list should correspond to blockCount.
|
|
71 12. blockStarts - A comma-separated list of block starts. All of the blockStart positions should be calculated relative to chromStart. The number of items in this list should correspond to blockCount.
|
|
72 13. expCount - The number of experiments.
|
|
73 14. expIds - A comma-separated list of experiment ids. The number of items in this list should correspond to expCount.
|
|
74 15. expScores - A comma-separated list of experiment scores. All of the expScores should be relative to expIds. The number of items in this list should correspond to expCount.
|
|
75
|
|
76 **GFF format** General Feature Format is a format for describing genes and other features associated with DNA, RNA and Protein sequences. GFF lines have nine tab-separated fields::
|
|
77
|
|
78 1. seqname - Must be a chromosome or scaffold.
|
|
79 2. source - The program that generated this feature.
|
|
80 3. feature - The name of this type of feature. Some examples of standard feature types are "CDS", "start_codon", "stop_codon", and "exon".
|
|
81 4. start - The starting position of the feature in the sequence. The first base is numbered 1.
|
|
82 5. end - The ending position of the feature (inclusive).
|
|
83 6. score - A score between 0 and 1000. If there is no score value, enter ".".
|
|
84 7. strand - Valid entries include '+', '-', or '.' (for don't know/care).
|
|
85 8. 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 '.'.
|
|
86 9. group - All lines with the same group are linked together into a single item.
