Hello Augusto,

To begin the troubleshooting process, it would be helpful if you 
would first do the following:

1) obtain a new copy of the executable using ftp 
(not a download from a browser) or the latest source 
code and compile locally

Options and instructions located at:
http://hgdownload.cse.ucsc.edu -> Source Downloads

2) Confirm that all input files and the chrom.sizes file
are based on the same version of the human genome
assembly. I know that you mentioned checking the
chrom lengths - we are wondering if you used the 
utility bedClip? If not, running this as a double check 
would help identify problems with bed entries that fall 
outside of the expected lengths, which may in turn lead 
to the discovery that data is from a different version a 
human genome assembly (it will also make it usable, 
whether from the same assembly or not, but the results 
would be mapped to an incorrect genomic reference sequence).

3) Re-run the analysis. If problems persists, please send 
us your complete command-line, input file (including chrom.sizes)
and output using the smallest dataset that you can create 
that still produces the error. Also include information about
your environment (server OS version, etc.) If the input file is 
large, please provide instructions for how/where to ftp the data
from your work site. Then we will duplicate your steps,
debug here, and provide feedback.

We appreciate your helping in discovering the root cause of
the error. All data can be sent directly to me (not the entire
mailing list) and I will forward to our team internally for help.

Jennifer
