Hi,

I'm Guru from Galaxy team, and one of our users has pointed out an  
issue with the liftOver tool which uses your liftOver binary. The  
problem seems to be with input datasets containing 6 columns. The  
output dataset in such cases will contain the 1st 5 columns intact,  
but only the 1st character of the 6th column for some reason. Can you  
please explain why this is the case?
I'm pasting sample input and output below for mm9 to hg18 mapping:
Input:
chr3    45665675        49665675        +       3-47575860      abcd
chr3    45665875        49675675        +       4-47575860      abcde

Output:
chr4    134785199       138758353       +       3-47575860      a
chr4    134785199       138767293       +       4-47575860      a

Also, I noticed that if I change the -bedPlus option of liftOver  
binary to 3 (I'm guessing the default is 6?), it works fine. Could  
you please elaborate a little bit about this option?

Thanks,
Guru.
