Error extracting features

[DanXieJY]

Hi, I've been trying to use the newly updated SlicerRadiomics package to extract radiomics features, but the error below prompted every time I clicked apply. There were only table titles in the tables. At first I thought it was due to the setting of my machine. But after I tried 3 different machines, including win and linux, the same thing happened. I've tried Slicer 5.3-5.6, and even manually changed the py files but nothing worked. Hope someone could help me fix this problem. Thanks!!

It looks like this needs to be updated to use the new syntax - is that what you tried?

Yes, I've tried that but the new error prompted:

It looks like with this tool you need to explicitly import the YAML object:

https://yaml.readthedocs.io/en/latest/basicuse/#basic-usage

If you get it working could you post a pull request?

Thank you for the quick response. I tried adding "from ruamel.yaml import YAML" to the top of the init.py file, but another error came. Sorry I'm very new to this area and hope for further guidance.

I'm not too familiar with this package either, but based on the message I think you need to pass it an open file not the name of the file. So something like:

schemaFile, schemaFuncs = radiomics.getParameterValidationFiles()
with open(schemaFile) as schema:
    settingsSchema = yaml.safe(schema)['mapping']['setting']['mapping']

If you can't find a combination that works, next time post your changed code along with the error message to make debugging clearer.

I finally made it run successfully!! Thank you for the precious advice. Below is what I changed to https://github.com/AIM-Harvard/pyradiomics/blob/master/radiomics/scripts/__init__.py

1. Add the code below to the top of the file: from ruamel.yaml import YAML
2. Add the code below before line 353: yaml = YAML(typ='safe', pure=True)
3. Change what was in line 353 to: settingsSchema = yaml.load(schema)['mapping']['setting']['mapping']

Thanks for reporting back with the solution 👍

Would you be able to make a pull request to update the repository with these changes?

For sure! I am now trying to pull a request. Thanks again for the help!

Hi there. Recently I've been trying to use the SlicerRadiomics to extract radiomics features and I also got this problem. I only got table title in the result table. I'm using a Slicer 5.7.0 and a SlicerRadiomics version c29d8a7 (2024-01-01) on Windows 11. So how can I fix this problem or bypass the problem? Thank you for your attention!

[pieper]

I tried yesterday with the windows stable and got a more recent radiomics code that worked.

I wasn't able to get a more recent build for the current stable 5.6.1 though, so maybe there's a configuration issue or something wrong with the extension update mechanism. @jcfr or @lassoan have you seen extension update issues?

[lassoan]

Most likely the problem is that the SlicerRadiomics superbuild specifies pyradiomics version using the branch name origin/master instead of a hash. The package manager is smart enough that it will not download and build a package again if it has that package already.

The fix is to change origin/master to the latest hash (146e3bd0971336913f9c9f49ce535bc4663ca5c2) in External_python-pyradiomics.cmake.

Thanks Andras, let's give that a try. 👍

Thank you all for your remarkable work. I've downloaded the Slicer 5.0.2 and used the compatible SlicerRadiomics, and it worked well on my computer. I guess I should stick to the older version for now. Thanks again!

[lassoan]

The fix works well! You can update SlicerRadiomics extension in the Extensions Manager in Slicer-6.1.
