Hello Lilach,
Currently, the human reference genome indexed for the GATK-beta tools is
'hg_g1k_v37'. The GATK-beta tools are under active revision by our team,
so we expect there to be little to no change to the beta version on the
main public instance until this is completed.
Attempting to convert data between different builds is not recommended.
These tools are very sensitive to exact inputs, which extends to naming
conventions, etc. The best practice path is to start and continue an
analysis project with the same exact genome build throughout.
If you want to use the hg19 indexes provided by the GATK project, a
cloud instance is the current option (using a hg19 genome as a 'custom
genome' will exceed the processing limits available on the public Galaxy
instance). Following the links on the GATK tools can provide more
information about sources, including links on the GATK web site which
will note the exact contents of the both of these genome versions,
downloads, and other resources.
Hopefully this helps to clear up any confusion,
Best,
Jen

Hi Jennifer,
Thank you for this reply.
I made a new BWA file, this time using the hg19(full) genome.
However, when I am trying to use DepthOfCoverage, the reference genomr
is stucked on the hg_g1k_v37 (this is the only option to select), and
I cannot change it to hg19(full). Most probably, because I selected
hg_g1k_v37 in the previous time I tried to use DepthOfCoverage.
It seems as a bug? How can I change it?
Thanks,
Lilach

Hi Lilach,
The problem with this analysis probably has to do with a mismatch
between the genomes: the intervals obtained from UCSC (hg19) and
the BAM from your BWA (hg_g1k_v37) run.
UCSC does not contain the genome 'hg_g1k_v37' - the genome
available from UCSC is 'hg19'.
Even though these are technically the same human release, on a
practical level, they have a different arrangement for some of the
chromosomes. You can compare NBCI GRCh37
<http://www.ncbi.nlm.nih.gov/genome/assembly/2758/> with UCSC
hg19 <http://genome.ucsc.edu> for an explanation. Reference
genomes must be /exact/ in order to be used with tools - base for
base. When they are exact, the identifier will be exact between
Galaxy and the source (UCSC, Ensembl) or the full Build name will
provide enough information to make a connection to NCBI or other.
Sometimes genomes are similar enough that a dataset sourced from
one can be used with another, if the database attribute is changed
and the data from the regions that differ is removed. This may be
possible in your case, only trying will let you know how difficult
it actually is with your analysis. The GATK pipeline is very
sensitive to exact inputs. You will need to be careful with genome
database assignments, etc. Following the links on the tool forms
to the GATK help pages can provide some more detail about expected
inputs, if this is something that you are going to try.
Good luck with the re-run!

Hi,
I am trying to used Depth of Coverage to see the coverages is
specific intervals.
The intervals were taken from UCSC (exons of 2 genes), loaded to
Galaxy and the file type was changed to intervals.
I gave to Depth of Coverage two BAM files (resulted from BWA,
selection of only raws with the Matching pattern: XT:A:U, and
then SAM-to-BAM)
and the intervals file (in advanced GATK options).
The consensus genome is hg_g1k_v37.
I got the following error message:

I will be grateful for any help.
Thanks!
