Hi, Recently, I tried to run galaxy on our cluster and got the following error messages when I was trying to run samtools. Everything is running well when I run it on a local machine. Once I switch it to cluster, the conversion could not be successfully executed. I checked the version of python, they are all v2.6.6 on both head and nodes machines. Anybody can help me on this issue? Thanks a lot in advance! ================================================== Traceback (most recent call last): File "/home/gxu/galaxy_dist/tools/samtools/bam_to_sam.py", line 10, in <module> from galaxy import eggs File "/home/gxu/galaxy_dist/lib/galaxy/__init__.py", line 5, in <module> __import__( "pkg_resources" ).declare_namespace( __name__ ) File "/home/gxu/galaxy_dist/lib/pkg_resources.py", line 698, in <module> class Environment(object): File "/home/gxu/galaxy_dist/lib/pkg_resources.py", line 701, in Environment def __init__(self, search_path=None, platform=get_supported_platform(), python=PY_MAJOR): File "/home/gxu/galaxy_dist/lib/pkg_resources.py", line 96, in get_supported_platform plat = get_build_platform(); m = macosVersionString.match(plat) File "/home/gxu/galaxy_dist/lib/pkg_resources.py", line 221, in get_build_platform from distutils.util import get_platform ImportError: No module named distutils.util ==================================================
