WebAn essential piece of information for DWI processing is the diffusion-weighted (DW) gradient scheme, also known as the “ DW gradient table ”, the “ DW encoding ”, the “ b-vectors ”, the “ bvecs ”, and other variations on the theme. WebThe dwifslpreproc command handles motion and distortion correction for DWI data (including eddy current distortions and optionally susceptibility-induced EPI distortions).

WebRunning eddy. Running eddy is a little bit more complicated than running for example its predecessor eddy_correct. The reasons for this are. eddy attempts to combine the correction for susceptibility and eddy currents/movements so that there is only one single resampling. This means we need to "inform" eddy of the results from topup (which is ... WebA call to topup will typically look something like. topup --imain=all_my_b0_images.nii --datain =acquisition_parameters.txt --config =b02b0.cnf --out=my_output. where all_my_b0_images.nii is a 4D image file containing all the data I want to use for the estimation of the field.
