To UCSC genome browser team,
I've recently encountered duplicated records in DARNED track (Human RNA
editing track) of version hg19.
In hg18 version there were 42055 records, all of them unique.
However, when I used hg19 version, I've noticed that there are 42045
records with 42039 unique records (wc -l Darned.hg19.bed => 42045 but  cat
Darned.hg19.bed | sort| uniq | wc -l => 42039).
When I visualized these regions in the genome browser they are shown as 2
elements with the same genomic position and the same name.
Is this problem a result of liftover between genome versions and
non-updated track?

The non-unique records are:
#The record in Darned.hg19.bed > number of times in the file
chr16    22517492    22517493    chr16.22517493    1000    +    22517492
22517493  >   2
chr17    36333356    36333357    chr17.36333357    1000    -    36333356
36333357   > 2
chr17    36332281    36332282    chr17.36332282    1000    -    36332281
36332282   > 2
chr17    36333402    36333403    chr17.36333403    1000    -    36333402
36333403   > 2
chr17    36333367    36333368    chr17.36333368    1000    -    36333367
36333368  >  2
chr17    36333372    36333373    chr17.36333373    1000    -    36333372
36333373   >  2

I know it sounds petty but I just note this for better curation of this
track.
