Dear all
I have been trying to use the example code in python/examples/loadProject.py
to load a ccpn project into memory independant of analysis. I have the
following version that works

from memops.general.Io import loadXmlProjectFile
from memops.general.Io import getTopDirectory
from memops.universal.Io import joinPath
from memops.general.Io import validateProjectPaths

if __name__ == "__main__":

  #
  # Load a CCPN project
  #

  projectDir = '/usr/torchwood/nmr/xxx/spectra/backbone'
  projectFileName = 'xxx_side_26_gst_viol_wim.xml'

  ccpnProject = loadXmlProjectFile(file = os.path.join
(projectDir,projectFileName))
  os.chdir (projectDir)

  validateProjectPaths(ccpnProject)


  print "List of molSystem objects:", ccpnProject.sortedMolSystems()
  for molSys in ccpnProject.sortedMolSystems():
    print "MolSystem name:", molSys.name
    print "MolSystem code:", molSys.code

however, if the os.chdir(projectDir) statement (which I added) isn't there i
get the following error

Traceback (most recent call last):

help ;-)
