Radiomic features with identical values

Dear Community Members,

I do not have too much prior experience with pyradiomics, so sorry for the dull question.

I have several features with identical values and I’d like to know if it’s ok, or not.

Examples:
In Gray Level Size Zone Matrix (GLSZM) Features:
Small Area Low Gray Level Emphasis (SALGLE) is equal with Small Area High Gray Level Emphasis (SAHGLE) and with Zone Entropy (ZE).

original_glrlm_ShortRunHighGrayLevelEmphasis and original_glrlm_ShortRunLowGrayLevelEmphasis and original_glszm_GrayLevelNonUniformity are also equal.

Is this normal?

Thank you,

Gergő

Up!

Any help would be appreciated.

Thank you,
