DWI grouping for sub-01
=======================

Output "sub-01_dir-AP" (MultipartID auto+concat+0 [inferred]): 1 series
  Distortion group sub-01_dir-AP (PE j-, TRT 0.05s):
    - sub-01_dir-AP_dwi.nii.gz
    corrected by: auto+unpile [inferred]

Fieldmap estimations:
  auto+unpile [inferred]: unpile fieldmap-less (experimental)
    - sub-01_T2w.nii.gz

Processing preview: eddy + TOPUP (--hmc-method eddy --sdc-method topup)
-----------------------------------------------------------------------

Output "sub-01_dir-AP" (1 single series):
  1. The series is denoised.
  2. eddy corrects head motion and eddy currents.
  3. unpile fits the susceptibility field by matching the eddy-corrected b=0 to the T2w (sub-01_T2w.nii.gz) with a model of the EPI readout, fitting the position of the T2w at the same time, and the field is applied to unwarp the eddy output.
  4. The corrected series is written as one output file.

Processing preview: TORTOISE + DRBUDDI (--hmc-method tortoise --sdc-method drbuddi)
-----------------------------------------------------------------------------------

Output "sub-01_dir-AP" (1 single series):
  1. The series is denoised.
  2. TORTOISE DIFFPREP corrects head motion and eddy currents.
  3. unpile fits the susceptibility field by matching the DIFFPREP-corrected b=0 to the T2w (sub-01_T2w.nii.gz) with a model of the EPI readout, fitting the position of the T2w at the same time, and the field is applied to unwarp the DIFFPREP output.
  4. The corrected series is written as one output file.

Processing preview: eddy + TOPUP→DRBUDDI (--hmc-method eddy --sdc-method topup+drbuddi)
---------------------------------------------------------------------------------------

Output "sub-01_dir-AP" (1 single series):
  1. The series is denoised.
  2. eddy corrects head motion and eddy currents. With no reverse phase-encoded dMRI series the DRBUDDI second stage does not run.
  3. unpile fits the susceptibility field by matching the eddy-corrected b=0 to the T2w (sub-01_T2w.nii.gz) with a model of the EPI readout, fitting the position of the T2w at the same time, and the field is applied to unwarp the eddy output.
  4. The corrected series is written as one output file.
  !! WARNING [mixed-non-pepolar]: Estimation 'auto+unpile' is not PEPOLAR; the DRBUDDI second stage only refines PEPOLAR corrections, so 'sub-01_dir-AP' will get single-stage correction.

Processing preview: SHORELine + DRBUDDI (--hmc-method shoreline --sdc-method drbuddi)
-------------------------------------------------------------------------------------

Output "sub-01_dir-AP" (1 single series):
  1. The series is denoised.
  2. SHORELine iteratively corrects head motion by registering each volume to a 3dSHORE signal-model prediction (eddy currents are not corrected).
  3. unpile fits the susceptibility field by matching the SHORELine-corrected b=0 to the T2w (sub-01_T2w.nii.gz) with a model of the EPI readout, fitting the position of the T2w at the same time, and the field is applied to unwarp the corrected series.
  4. The corrected series is written as one output file.
