Hi, Libia.

Intersection results are always in terms of the first table, so if you're
looking for information regarding conservation, you should start with the
conservation table and then intersect it with UCSC Genes.  When you create
the intersection in this order, the last column will be the conservation
score (log odds score).

As an aside, if you were using the identifiers function to define your
genes/regions, you will now have to use the define regions button. Note that
you can only define 1,000 regions this way - you will need to use a custom
track if you have more genes than that. Please write back if you need
assistance with this.

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

Subject: [Genome] Log odds score for any conserved element in a gene

Hello,

I'm trying to collect the log odds score for any conserved element in a gene
by intersecting two tables but I'm unable to get an actual log score.

After selecting the chromosomal position of the genes I want I go to Tables.
Then Under gene and Gene Prediction Tracks, UCSC Genes, I intersect the
position I want with phastConsElements46wayPlacental, but the excel file I
gather has no log odds scores.

The BED table shows me the number of exons, the number of base pairs in each
exon, and also some values which I'm unable to interpret that are related to
the number of exons. Are these values the phastCon score presenting the
exons of each gene? If so, why is the first number always 0?

Is this the correct way of gathering the data I want (a conserve score for
each gene), if so why am I not getting a score? If I'm doing this wrong I
would appreciate any feedback on how to do it better.


Thanks,

Libia
