[galaxy-user] Velvetoptimiser error

Dear Galaxy users,

Has anyone worked with velvetoptimiser tool from the Tool shed? I have been trying both the stable and the test version of the velvetoptimiser tool and i keep getting the same error:

Traceback (most recent call last): File "/home/ladoukef/galaxy_dist/tools/myTools/velvetoptimiser/velvet_optimiser.py", line 102, in if __name__ == "__main__": __main__() File "/home/ladoukef/galaxy_dist/tools/myTools/velvetoptimiser/velvet_optimiser.py", line 67, in __main__ for line in open(contigs_path ): IOError: [Errno 2] No such file or directory: 'contigs.fa'

Can someone identify where the error is? The file missing (contigs.fa) is supposed to be built by the tool itself.

Thank you, Efthymios Ladoukakis
