[FEAT EXTRACTION]: glrm & glcm only return 1 value instead of 14 (13 directions + mean)

[LHuysmans]

Describe the bug When calculating the radiomics features, I expect to get multiple values for the glrm and glcm features as they are directional dependent (13 directions + mean). When I run the code below, I don't get any errors but the glrm and glcm features only contain 1 value instead of 14 (or 13?). What am I doing wrong?

PyRadiomics configuration setting: binWidth: 13 label: 1 normalize: True interpolator: 'sitkBSpline' resampledPixelSpacing: weightingNorm:

imageType: Original: {}

featureClass: shape: firstorder: glcm: ngtdm: glrlm: glszm: gldm:

To Reproduce from radiomics import featureextractor image_file_path = ... segm_file_path = ... extractor = featureextractor.RadiomicsFeatureExtractor(param_file) result = extractor.execute(image_file_path, segm_file_path)

Version (please complete the following information):

• OS: Windows 10
• Python version: 3.6.13
• PyRadiomics version: 3.0.1
• numpy version: 1.19.5
• numpy-base version: 1.16.6

The values are averaged across directions.

@JoostJM And how can I get the values per direction? Or is this not possible?
