Hello Vince,

There is still not a way to get the Short Match track into a custom 
track (or some other text format) via the Genome Browser or the Table 
Browser.

There is a command-line tool called findMotif in the source tree that 
you could use.  The source can be obtained from:
http://hgdownload.cse.ucsc.edu/admin/jksrc.zip

Instructions for building the source:
http://genome.ucsc.edu/admin/jk-install.html
(note that you would not need to do step 7)

The program is located in src/utils/findMotif/.  Run it without 
arguments to get this usage statement:

$ findMotif
findMotif - find specified motif in sequence
usage:
    findMotif [options] -motif=<acgt...> sequence
where:
    sequence is a .fa , .nib or .2bit file or a file which is a list of 
sequence files.
options:
    -motif=<acgt...> - search for this specified motif (case ignored, 
[acgt] only)
    -chr=<chrN> - process only this one chrN from the sequence
    -strand=<+|-> - limit to only one strand.  Default is both.
    -bedOutput - output bed format (this is the default)
    -wigOutput - output wiggle data format instead of bed file
    -verbose=N - set information level [1-4]
    NOTE: motif must be longer than 4 characters, less than 17
    -verbose=4 - will display gaps as bed file data lines to stderr

If you have further questions, please feel free to contact us again at
