Hello Fenglei He,

You can convert your UCSC identifiers using the table browser 
(http://genome.ucsc.edu/cgi-bin/hgTables).

After selecting your assembly of interest (mm9) select:

     group: Genes and Gene Prediction Tracks
     track: UCSC Genes
     table: kgXref

Then you can either paste in your list of identifiers or upload them as 
a text file (in the "identifiers (names/accessions)" section). Then select:

     output format: "selected fields from primary and related tables"

Once you click on "get output" this will take you to a menu where you
can specify which fields (i.e. gene symbol) you want to retrieve from 
your tables of interest.

Hopefully this information was helpful and answers your question. If you 
have further questions or require clarification feel free to contact the 
mailing list at [email protected].

Regards,

Pauline Fujita
