Access denied error when running TotalSegmentator

[nforwood]

Hi everyone, I was previously able to run the total segmentator but today I am getting an access denied error in the early stages of running.

The final message I get is
PermissionError: [WinError 5] Access is denied: 'C:\\Users\\------\\AppData\\Local\\Temp\\tmp3sifet_4\\dicom

All of this code worked perfectly yesterday but today its failing. Ive checked that I have access to that folder and I tried to execute the code under an administrator account but I get the same error.

Any clues?

the full trace back is:

Unfortunately I have no idea what the reason might be.

run as admin when open pycharm may help

@nforwood Have you solved your problem? I also encountered a similar problem when running on Windows.

Not an actual fix to the problem, but the following workaround should work:

1. Open the file convert_dicom.py (your path from above: C:\Users-------0\OneDrive -------\Research\Splenic Flexure.venv\Lib\site-packages\dicom2nifti\convert_dicom.py)
2. Search for "rmtree" and remove the whole "finally" block where it calls shutil.rmtree(temp_directory)

    finally:
        # remove the copied data
        shutil.rmtree(temp_directory)

3. Run it again.

Your TEMP folder will eventually fill up though, so you may want to clean it manually.

Thank you for your reply! I tried to remove the read-only attribute of the source folder, and then it worked properly. 程辉 ***@***.*** 签名由 网易灵犀办公 定制 Original: From：Matias Lavik ***@***.***>Date：2025-03-13 04:18:55(中国 (GMT+08:00))To：wasserth/TotalSegmentator ***@***.***>Cc：chzuhuich ***@***.***> , Comment ***@***.***>Subject：Re: [wasserth/TotalSegmentator] Access denied error when running TotalSegmentator (Issue #391)Not an actual fix to the problem, but the following workaround should work: Open the file convert_dicom.py (your path from above: C:\Users-------0\OneDrive -------\Research\Splenic Flexure.venv\Lib\site-packages\dicom2nifti\convert_dicom.py) Search for "rmtree" and remove the whole "finally" block where it calls shutil.rmtree(temp_directory) finally: # remove the copied data shutil.rmtree(temp_directory) Run it again.Your TEMP folder will eventually fill up though, so you may want to clean it manually. — Reply to this email directly, view it on GitHub, or unsubscribe.
