    PSL File Format - Definition and supported options

    PSL lines represent alignments, and are typically generated by BLAT. Each line consists of 21 required fields, and track lines may optionally be used to provide more information.

    Fields

    Fields are space-separated, and all 21 are required.

    1. matches - Number of matching bases that aren't repeats.
    2. misMatches - Number of bases that don't match.
    3. repMatches - Number of matching bases that are part of repeats.
    4. nCount - Number of 'N' bases.
    5. qNumInsert - Number of inserts in query.
    6. qBaseInsert - Number of bases inserted into query.
    7. tNumInsert - Number of inserts in target.
    8. tBaseInsert - Number of bases inserted into target.
    9. strand - defined as + (forward) or - (reverse) for query strand. In mouse, a second '+' or '-' indecates genomic strand.
    10. qName - Query sequence name.
    11. qSize - Query sequence size.
    12. qStart - Alignment start position in query.
    13. qEnd - Alignment end position in query.
    14. tName - Target sequence name.
    15. tSize - Target sequence size.
    16. tStart - Alignment start position in query.
    17. tEnd - Alignment end position in query.
    18. blockCount - Number of blocks in the alignment.
    19. blockSizes - Comma-separated list of sizes of each block.
    20. qStarts - Comma-separated list of start position of each block in query.
    21. tStarts - Comma-separated list of start position of each block in target.

    Track lines

    Although not part of the formal PSL specification, the WormBase ParaSite browser will use track lines to further configure sets of features. Track lines should be placed at the beginning of the list of features they are to affect.

    The track line consists of the word 'track' followed by space-separated key=value pairs - see the example above. Valid parameters used by the WormBase ParaSite browser are:

    • name - unique name to identify this track when parsing the file
    • description - Label to be displayed under the track in Region in Detail
    • priority - integer defining the order in which to display tracks, if multiple tracks are defined.
