Hi Lilach,

I have been dealing with these issues for some time now.

The only genome you can use with Picard and GATK tools in Galaxy is
hg_g1k_v37. I think this is why.

From GATK Wiki[1]:
"If you are using human data, your reads must be aligned to one of the
official b3x (e.g. b36, b37) or hg1x (e.g. hg18, hg19) references. The
contig ordering in the reference you used must exactly match that of
one of the official references canonical orderings. These are defined
by historical karotyping of largest to smallest chromosomes, followed
by the X, Y, and MT. The order is thus 1, 2, 3, ..., 10, 11, 12, ...
20, 21, 22, X, Y, MT. The GATK will detect misordered contigs (for
example, lexicographically sorted) and throw an error. This draconian
approach, though unnecessary technically, ensures that all
supplementary data provided with the GATK works correctly. You can use
ReorderSam to fix a BAM file aligned to a missorted reference
sequence."

So far what I have done when presented with a BAM file produced with
reference with lexicographical chromosomes ordering, is to use
Picard's ReorderSam tool, also in Galaxy, selecting hg_g1k_v37 as
reference. You might not be able to this, as if a recall correctly
hg19 also use chr1, chr2... instead of 1, 2, ... In that case more
work needs to be done and at that point is almost easier to just remap
with the correct reference for use with GATK. In your case it seems
you already have it. What you might need to do is resort your
intervals file and probably change the chromosomes identifiers, this I
think can be done inside Galaxy.

I would love to hear comments about this approach, as sometime I do
worry like Hiram's comment hints to, that hg19 and hg_g1k_v37 might
not be completely identical beside the chromosome ordering. In that
case my resorted BAM or intervals files might be incorrect.

Hope it helps,
Carlos
