Origin Ver. 2021 (64-bit) and Service Release (Select Help-->About Origin): 9.8.0.200
Operating System: Windows 10 Pro
Hello,
When I'm trying to excecute the batch fitting example provided by Origin (first example at https://www.originlab.com/doc/en/python/Examples/Analysis) I get the following Error:
Traceback (most recent call last):
File "C:\ProgramData\OriginLab\98\PyPackage\Py3\originpro\analysis.py", line 21, in __init__
self._trfdf = ET.fromstring(po.LT_get_str(f'GetFDFAsXML("{self.func}")$'))
File "C:\Program Files\OriginLab\Origin2021\Python38.zip\xml\etree\ElementTree.py", line 1321, in XML
xml.etree.ElementTree.ParseError: no element found: line 1, column 0
The above exception was the direct cause of the following exception:
Traceback (most recent call last):
File "<string>", line 6, in <module>
File "C:\Users\Phd02\Documents\OriginLab\Anwenderdateien\batchfittingexample.py", line 30, in <module>
model = op.NLFit('Gaussian')
File "C:\ProgramData\OriginLab\98\PyPackage\Py3\originpro\analysis.py", line 23, in __init__
raise ValueError(f'Invalid fitting function: {func}') from e
ValueError: Invalid fitting function: Gaussian
It seems to me that the Programm can't find the fdf file, but i could'nt find a solution to the Problem.
Edit: the same sample code worked on a different PC. So the Problem turned out to be an installation issue. Upgrading Origin, repairing files and a complete reinstallation did not solve the issue on the first PC though. Any help would still be appreciated.
Thanks for any help in advance. |

Hello Chao,
you were right. I could upgrade to ver. 2021b which resolved my issue. Thank you! |

Hello,
I'm thinking this may be an issue specific to 2021. Is the other computer also 2021?
If not, are you able to upgrade your Origin?
Best,

Hello,
the Gaussian.fdf file is present in my directory. I also tried to change to different fdf files/fit methods in that same directory with possible case sensitivity in mind.
I also tried to place the Gaussian.fdf file into the directory .../Samples/Batch2 as well as where the .py file is located. |

Hello,
It seems you may be missing the Gaussian.fdf file from C:\Program Files\OriginLab\Origin2021\FitFunc\Gaussian.fdf.
You could try copying the Gaussian.fdf from the working computer to the first PC.
Best,
Chao |
