Hello,

Yes, this can be done using the table browser. The positions will be those 
repeat annotations that overlap with your regions having coordinates anchored 
to the genomic reference sequence.

To do this, 
1) Create a custom track (BED format) of your regions and save back to browser
2) Start with the RepeatMasker track and perform and intersection against the 
custom track
3) Download or save output back as another custom track.

http://genome.ucsc.edu/goldenPath/help/hgTracksHelp.html#CustomTracks
http://genome.ucsc.edu/FAQ/FAQformat#format1


To do a full join (and to link a specific entry from the RepeatMasker track 
with a specific entry from the custom track of coordinates), send both datasets 
to Galaxy and do a full join based on coordinate overlap (by checking Galaxy as 
the output option in the Table browser).

The table rmsk (the primary table for the RepeatMasker track) contains the 
fields repName, repClass, and repFamily. For even more details, link out to the 
data's source at http://www.repeatmasker.org/

Thanks,
Jennifer
