Generating SRC files
use –action=
src
to generate SRC file from NIFTI or DICOM files
Examples
Convert one 4d NIFTI file and generate an SRC file subject001.nii.gz.src.gz
dsi_studio --action=src --source=c:\subject001.nii.gz
Convert one 4d NIFTI file and specify the location of bval and bvec (only needed when DSI Studio cannot find them)
dsi_studio --action=src --source=c:\subject001.nii.gz --bval=bval --bvec=bvec
Combine two 4d NIFTI files and generate one SRC file
dsi_studio --action=src --source=HCA9992517_V1_MR_dMRI_dir98_AP.nii.gz --other_source=HCA9992517_V1_MR_dMRI_dir99_AP.nii.gz
Search all DICOM files under the assigned directory and output SRC file
dsi_studio --action=src --source=C:\20081006_11_00814348_DWI_WIP_DSI_203 --output=c:\20081006_11_00814348_DWI_WIP_DSI_203.src.gz
Find all *98_AP.nii.gz file and combine its corresponding 99_AP.nii.gz file to generate one combined SRC file
dsi_studio --action=rec --source=*98_AP.nii.gz --other_source=*99_AP.nii.gz
Parse all 4d NIFTI files in a folder (each of them has a bval and bvec file that shares a similar file name) and generate corresponding SRC files to a new folder
dsi_studio --action=src --source=*.nii.gz --output=/src_folder
Windows batch file for creating src files from HCP datasets

cd F:\HCP\

for /f "delims=" %%x in (file_list.txt) do (
call dsi_studio.exe --action=src --source=F:\HCP\%%x\T1w\Diffusion\data.nii.gz --output=F:\%%x.src.gz > F:\%%x.txt
)

Core Functions
Parameters | Description |
---|---|
source | Specify a directory storing DICOM files or the path to one 4D NIFTI file |
Optional Functions
Parameters | Description |
---|---|
other_source | specify other files to be included in the SRC file. Multiple files can be assigned using comma separator, (e.g. –other_source=1.nii.gz,2.nii.gz) |
output | assign the output src file name (.src.gz) or the output folder |
b_table | assign the text file to replace b-table |
bval | specify the location of the FSL bval filea |
bvec | specify the location of the FSL bvec filea |
afor most cases, DSI Studio can automatically associate bval and bvec with NIFTI automatically.
Accessory Functions
Parameters | Default | Description |
---|---|---|
recursive | 0 |
search all NIFTI or DICOM files under the directory specified in –source |
up_sampling | 0 |
upsampling the DWI, 0 :no resampling, 1 :upsample by2, 2 :downsample by2, 3 :upsample by 4, 4 :downsample by 4 |
