Algorithm parameters overview

algorParam.swismwi.	Description
m	Power to which the phase mask (derived from the susceptibility map) is raised, controlling the contrast/strength of the weighting mask
threshold	Susceptibility threshold (in ppm) used to build the paramagnetic/diamagnetic weighting mask from the susceptibility map
ismIP	Enable minimum intensity projection (mIP) of the SMWI image over a number of slices
slice_mIP	Number of slices used to compute the minimum intensity projection (mIP), when ismIP is enabled
isParamagnetic	Save the paramagnetic weighted images
isDiamagnetic	Save the diamagnetic weighted images

Power to which the phase mask (derived from the susceptibility map) is raised, controlling the contrast/strength of the weighting mask
