#6 atac.pl => empty results file

[malcolm cook]

I am running the svn head on atac on the contig output of two assemblies --
they are the "LargeContigs.fna" from roche/newbler assemblies of 454
results.
The stderr output (attached) reports "finished" and provides path to .atac
and clumps.atac files. completion.
Examination of these files however shows they only contain the header.
There is no tabular data.
Any suggestions for how to diagnose would be very welcome.
