i’m trying to load volume in python scriptable module script

code :[success, loadedVolumeNode] = slicer.util.loadVolume(path, returnNode=True)

error :

Traceback (most recent call last):

Most likely the problem is that your path contains special characters (\A and \S, note that \ is an escape character). You can use any of these syntaxes instead:

  • r‘C:\Anand Work\Sft.nrrd’ => r prefix specifies raw string, \ is not interpreted as escape character in these strings
  • ‘C:\\Anand Work\\Sft.nrrd’ => double backslash encodes backslash
  • ‘C:/Anand Work/Sft.nrrd’ => forward slashes can be use instead of backslashes
