dmri_bids_config: Configure TRACULA to run on a BIDS-formatted dataset
Usage
dmri_bids_config --in <directory> -c <configfile>
This script will take as its input a BIDS-formatted study directory and output: 1. A TRACULA configuration file: This file is needed to pre-process the DWI data, reconstruct tracts of interest, etc. with trac-all. 2. A FreeSurfer Group Descriptor (FSGD) file: This file is needed to perform statistics on the output tract measures with mri_glmfit. It will be generated if the input BIDS directory contains a participants.tsv file. After you run dmri_bids_config It is important that you inspect the configuration file to make sure that everything has been set up the way you intended.
--in <directory> Path to the input data (the top-level BIDS directory for the study, not a single subject or session directory)
--c <file> Output configuration file that specifies DWI inputs and analysis options for TRACULA --f <file> Output FSGD file that specifies subject-specific continuous and discrete variables for linear regression analyses (default: append .fsgd to the argument of --c)
--fsdir <directory> FreeSurfer SUBJECTS_DIR for this study (must be specified, either here or with: setenv SUBJECTS_DIR ...) --trdir <directory> Output TRACULA directory for this study (If not specified, TRACULA will use the FreeSurfer SUBJECTS_DIR) --acq <name> Only use DWI scans collected with this acquisition (The name of the NIfTI volumes in BIDS must include the string acq- followed by this name)
