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:

A TRACULA configuration file: This file is needed to pre-process the DWI data, reconstruct tracts of interest, etc. with trac-all.
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.

--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)

--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)

It is important that you inspect the configuration file to make sure that everything has been set up the way you intended.
