# # dmrirc.long.example # # This example is applicable to longitudinal studies, where DWI data from # multiple time points are available for each subject. For a simple example # with a single DWI data set per subject, see dmrirc.example instead. # # This file contains commands that will be run by trac-all before an analysis. # It is used to set all parameters needed for the analysis. # # Remove a parameter from your dmrirc file if you want use the default value. # Parameters that don't have default values must be specified. # # Any other commands that you might want to run before an analysis can be added # to this file. # # Original Author: Anastasia Yendiki # CVS Revision Info: # $Author: ayendiki $ # $Date: 2013/12/05 23:08:54 $ # $Revision: 1.3 $ # # Copyright © 2011 The General Hospital Corporation (Boston, MA) "MGH" # # Terms and conditions for use, reproduction, distribution and contribution # are found in the 'FreeSurfer Software License Agreement' contained # in the file 'LICENSE' found in the FreeSurfer distribution, and here: # # https://surfer.nmr.mgh.harvard.edu/fswiki/FreeSurferSoftwareLicense # # Reporting: freesurfer@nmr.mgh.harvard.edu # # # FreeSurfer SUBJECTS_DIR # T1 images and FreeSurfer segmentations are expected to be found here # setenv SUBJECTS_DIR /path/to/recons/of/ducks # Output directory where trac-all results will be saved # Default: Same as SUBJECTS_DIR # set dtroot = /path/to/tracts/of/ducks # Subject IDs (one per time point per subject) # set subjlist = ( huey-scan1 \ huey-scan2 \ dewey-scan1 \ dewey-scan2 \ louie-scan1 \ louie-scan2 ) # Longitudinal base template subject IDs (one for each time point above) # set baselist = ( huey \ huey \ dewey \ dewey \ louie \ louie ) # In case you want to analyze only Huey and Louie # Default: Run analysis on all time points and subjects # set runlist = (1 2 5 6) # Input diffusion DICOMs (file names relative to dcmroot) # If original DICOMs don't exist, these can be in other image format # but then the gradient table and b-value table must be specified (see below) # set dcmroot = /path/to/dicoms/of/ducks set dcmlist = ( huey/year1/dwi/XXX-1.dcm \ huey/year2/dwi/XXX-1.dcm \ dewey/year1/dwi/XXX-1.dcm \ dewey/year2/dwi/XXX-1.dcm \ louie/year1/dwi/XXX-1.dcm \ louie/year2/dwi/XXX-1.dcm ) # Diffusion gradient tables (if there is a different one for each scan) # Must be specified if inputs are not MGH DICOMs # The tables must have either three columns, where each row is a gradient vector # or three rows, where each column is a gradient vector # There must be as many gradient vectors as volumes in the diffusion data set # Default: Read from DICOM header # set bveclist = (/path/to/huey/year1/bvecs.txt \ /path/to/huey/year2/bvecs.txt \ /path/to/dewey/year1/bvecs.txt \ /path/to/dewey/year2/bvecs.txt \ /path/to/louie/year1/bvecs.txt \ /path/to/louie/year2/bvecs.txt) # Diffusion gradient table (if using the same one for all scans) # Must be specified if inputs are not MGH DICOMs # The table must have either three columns, where each row is a gradient vector # or three rows, where each column is a gradient vector # There must be as many gradient vectors as volumes in the diffusion data set # Default: Read from DICOM header # set bvecfile = /path/to/bvecs.txt # Diffusion b-value table # Must be specified if inputs are not MGH DICOMs # There must be as many b-values as volumes in the diffusion data set # Default: Read from DICOM header # set bvalfile = /path/to/bvals.txt # Perform registration-based B0-inhomogeneity compensation?
