Hello Sujata,

To extract non-coding alignments, use the Table browser along with Galaxy. Send 
the Conservation track's MAF output to Galaxy, a custom track of coordinates to 
Galaxy, then use the tools there to "slice" out regions. 
See the section Fetch Alignments:
http://g2.bx.psu.edu/

Just for your information, to extract coding regions from a MAF alignment, 
these are the instructions:
http://genome.ucsc.edu/goldenPath/help/hgTablesHelp.html#FASTA

Using the Table browser alone, you can however extract fasta formatted sequence 
from any assembly and then run your own BLAT to generate an alignment, tuning 
the parameters for your specific needs if using command-line BLAT.

Start with a track that has defined coding/non-coding regions if you need mRna 
sequence (Gene and Gene Predictions group - UCSC Genes would be the best 
choice). Then extract the sequence - either the mRna for the UTR region or the 
genomic reference sequence that was aligned to.
Table browser:

Instructions: http://genome.ucsc.edu/goldenPath/help/hgTablesHelp.html#Sequence

If you want to use the genomic reference sequence and know the coordinates (do 
not want to start with a Gene track), use these instructions.

Next, run a BLAT using our web server (for smaller projects) or configure your 
own and run it command-line (any unix platform).
BLAT documentation with links to resources:

Results from BLAT that you run independent of the Browser can be uploaded again 
as a custom track for more analysis if desired.

We hope this helps to get you started. If you need more assistance, please 
email the [email protected] mailing list directly as the team will be working 
together to answer questions over the next two weeks.
