Hi, See http://www.ncbi.nlm.nih.gov/pubmed/23668970 specifically Figure 9.
“dc” is the readout distortion correction. “restore” is the bias field correction (for the receive bias field) The gradient distortion correction is not included as part of the filename, so the file could just as well have been named “T1w_gdc_acpc_rdc_restore_brain.nii.gz” Cheers, -MH -- Michael Harms, Ph.D. ----------------------------------------------------------- Associate Professor of Psychiatry Washington University School of Medicine Department of Psychiatry, Box 8134 660 South Euclid Ave. Tel: 314-747-6173 St. Louis, MO 63110 Email: mha...@wustl.edu From: <hcp-users-boun...@humanconnectome.org> on behalf of X K <bnu...@gmail.com> Date: Tuesday, October 9, 2018 at 8:50 AM To: "hcp-users@humanconnectome.org" <hcp-users@humanconnectome.org> Subject: [HCP-Users] T1w_acpc_dc_restore_brain.nii.gz Hi, I am using the HCP data. Here I came across a question about the file T1w_acpc_dc_restore_brain.nii.gz I am curious what have been done between T1w.nii.gz and this file. From the document, I guess that acpc indicate linear registriation (flirt) with dof=6; dc might indicate distortion correction, but how was this done? using flirt with dof=12? I am not sure whether 'restore' has particiulat meaning. Thanks.
