Good Morning Stéphane:

Here are the liftOver chain files for both directions (five lines in each):

Liftover chain from chrM_rCRS to UCSC hg18/hg19 chrM:

chain 1550477 chrM_rCRS 16569 + 0 16569 chrM 16571 + 0 16571 230
310     0       2
2796    1       0
13075   0       1
387

Liftover chain from UCSC hg18/hg19 chrM to chrM_rCRS:

chain 1550477 chrM 16571 + 0 16571 chrM_rCRS 16569 + 0 16569 230
310     2       0
2796    0       1
13075   1       0
387

Subject: [Genome] need rCRS liftover files for hs.MT

I face a problem when trying to do population MT haplotyping from my NGS data.

Rationale:
The human MT sequence included in the h18 build (only one I checked so far) is 
not identical to the official MT reference used by the MITOMAP (rCRS = 
NC_012920.1)
Consequently, when I use MT snp-lists obtained by human full genome 
re-sequencing, I cannot operate haplotyping using MITOMAP related tools (apples 
compared to pears).

ClustalW results in
Aligned Length = 16572   Gaps = 3
Identities = 16528 (99%)

Request:
Is there an easy way to create a liftover file (type used by UCSC) in order to 
lift my variant lists to the rCRS reference and compare my populations to 
existing population data.
I found the UCSC liftover wiki pages but the 'chain and net' story is a bit 
hard to digest for me, I do not have blat running, and I am almost sure someone 
has already produced these liftover files.

Sorry if I overloked something!
Thanks a lot for your advice and help,
Stephane
