Hello, Edge.

I repeated the steps you provided and I did not encounter a discrepancy
between the coordinates of the two queries.  I would also like to add that
you do not need to set "group" to "All Tables" in order to use the rmsk
table.  You can set "group" to "Variation and Repeats" and set "track" to
"RepeatMasker".

If you would like the coordinates of 5' UTR and 3' UTR regions, you will
need to use a gene track like UCSC Genes or RefSeq Genes.  You can do so by
performing the following steps:

1. Set the following options:
Group: Genes and Gene Prediction Tracks
Track: UCSC Genes
Table: knownGene
Output format: sequence

2. Click the "get output" button

3. Select "genomic" and click the "submit" button

4. Check the "5' UTR Exons" and "3' UTR Exons" checkboxes and select any
other options you desire

5. Click the "get sequence" button

Note that the output here will not distinguish 5' UTR sequences from 3' UTR
sequences.  If you want to distinguish 5' UTR sequences from 3' UTR
sequences, you will want to make two separate queries.

Please contact us again at [email protected] if you have any further
questions.

Subject: [Genome] Help with extract rRNA, tRNA, 3'-UTR and 5'-UTR from UCSC
Genome Browser

Dear Professor,
Can I know that how to extract the information (such as chromosome number,
 position start and position ) of human hg19 3'-UTR,  5'-UTR, rRNA, tRNA
from UCSC Genome Browser?

I got extract rRNA and tRNA by using the following method:
        * Select "All Tables" from the group drop-down list
        * Select the "rmsk" table from the table drop-down list
        * Choose "GTF" as the output format / Choose "Sequence" as the
output format
        * Type a filename in "output file" so your browser downloads the
result
        * Click "create" next to filter
        * Next to "repClass," type rRNA
        * Next to free-form query, select "OR" and type repClass = "tRNA"
        * Click submit on that page, then get output on the main page

However, when I check the position of rRNA and tRNA in GTF format and
Sequence format.
It shown difference nucleotide.
Can I know how to solve this issue?
I just wanna to make sure the position of rRNA and tRNA in GTF format is
tally with the position and chromosome shown in Sequence format.
Can I know how to get all the info regarding human hg19 3'-UTR,  5'-UTR,
rRNA, tRNA from UCSC Genome Browser?

Many thanks for any advice.

best regards
