[galaxy-dev] getting an error message while running Generate pileup tool in NGS: SAM

Hi all, I am trying to run 'Generate pileup' tool from NGS: SAM Tool tracks in local galaxy instance. I am getting the desired output and the job status ends with and error message. Here is the error message: An error occurred running this job: *cp: cannot stat `/home/galaxy/galaxy-2.1.2009/database/files/_metadata_files/000/metadata_4.dat': No such file or directory* I compared the result from my local instance with main galaxy server and there is no difference at all. Please let me know anything wrong in my side. Many thanks in advance, Vipin T S
