Name
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.
Arguments
Required arguments
--in <directory>
Path to the input data (the top-level BIDS directory for the study, not a single subject or session directory)
At least one of the following two is required:
--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)
Optional arguments
--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)
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.
