rcTestingMatrix: rcTestingMatrix
In stnava/rcissus: Fast Segmentation Or Image Translation With Deep Learning

Build a rcissus testing matrix

1 2	rcTestingMatrix(x, masks, rcb, patchRadius = 3, meanCenter = FALSE, nsamples = 1000, seeds)

`x`	input filenames or image list defining one testing modality
`masks`	input filenames or image list defining testing modality masks
`rcb`	input image basis from `rcBasis`
`patchRadius`	patch radius, integer value
`meanCenter`	boolean
`nsamples`	number of samples per image
`seeds`	random seeds for reproducibility across testing modalities
