CaPTk radiomic feature extraction

Flywheel gear that implements CaPTk's application for single-subject radiomic feature extraction. Gear will output a CSV file with the subject's radiomic features within the tumor mask, for all of the input scans.

NOTE: input images must be co-registered

Normalization (to range 0-255) is an optional step.

Dependencies:

• CaPTk (gear uses the existing Docker container 2021.03.29)

Required inputs:

• Tumor segmentation mask (gear automatically binarizes input mask - all non-zero voxels become 1)

Optional inputs:

• T1
• T1CE
• T2
• FLAIR
• ADC
• Radiomic feature parameter file (if not specified, gear will use CaPTk's default 3D parameters)
• brain mask (for normalization step)

Optional configuration:

• subject label to use in the output file
• output file name (defaults to radiomic_features.csv)
• perform normalization (for T1/T1CE/T2/FLAIR inputs)
• use intersection of tumor segmentation & brain mask during normalization
