Error for ordering step

[clementmo]

My Lanchesis is compiled with samtools-0.1.19 and boost_1_54_0. After run for a while, the progress is aborted, with the following error in the log file.

"Loading contig RE lengths for use in normalization <- *****/cached_data/group0.CLM.RE_sites
MakeTrunkOrder!
min_len_reduced = 15, N_long_contigs = 1229
prim_minimum_spanning_tree (iteration #0, previous trunk_size = 0)
terminate called after throwing an instance of 'boost::exception_detail::clone_impl<boost::exception_detail::error_info_injectorboost::negative_edge >'
what(): The graph may not contain an edge with negative weight."

Under the directory out_putfile/cached_data/ , group*.CLM, group*.CLM.lens and group*.CLM.RE_sites have been generated, lacking group*.trunk.ordering.
Under the directory out_putfile/main_results/, only clusters.by_name.txt and clusters.txt are generated, lacking all the group*.ordering files.
What is the problem and how can I solve it?
Thank for someone who can provide solutions and suggestions!
