Hi All, I have a problem with WriteInputFiles module. It produces error message: Uncaught exception: "[Errno 2] No such file or directory: 'C:\\Program Files\\VisTrails\\Python27_64\\..\\lib\\xml\\ALPS.xsl'" Traceback (most recent call last): File "C:\Program Files\VisTrails\vistrails\core\modules\vistrails_module.py", line 372, in update self.compute() File "C:\Program Files\VisTrails\vistrails\packages\alps\tools.py", line 157, in compute pyalps.writeInputFiles(os.path.join(dir.name,base_name),l,baseseed) File "C:\Program Files\VisTrails\Python27_64\lib\site-packages\pyalps\tools.py", line 410, in writeInputFiles copyStylesheet(dirname) File "C:\Program Files\VisTrails\Python27_64\lib\site-packages\pyalps\tools.py", line 291, in copyStylesheet shutil.copyfile(xslPath(), target) File "C:\Program Files\VisTrails\Python27_64\lib\shutil.py", line 82, in copyfile with open(src, 'rb') as fsrc: IOError: [Errno 2] No such file or directory: 'C:\\Program Files\\VisTrails\\Python27_64\\..\\lib\\xml\\ALPS.xsl' I have installed: alps-2.2.b1-win64 vistrails-x64-setup-2.1 alps-vistrails-2.2.b1-win64 on Windows 7 Professional in the default directiories and I let the APLS modify the PATH variable.
