Denoising options

just parking this here for later

wavelet denoising

I had some success (#TODO add examples) with wavelet denoising recently

I came across this as Afni's 3dDespike gave some strange artefacts. The video above gives some theoretical reasons against using 3dDespike -like techniques.

FYI: on mac os the compilation was a bit tricky, I had to modify mexopts.sh to point to the correct Xcode compiler; Linux no issues

	CC='xcrun  -sdk macosx10.9  clang' 
	MW_SDK_TEMP="find `xcode-select -print-path` -name MacOSX10.9.sdk" 
	MACOSX_DEPLOYMENT_TARGET='10.9' 
	CXX='xcrun  -sdk macosx10.9  clang++'

PCA-based denoising

This worked really well with experiments that have multiple, similar runs (i.e., pRF mapping)
