Hi all,
I’m new to learn fmriprep relevant knowledge, now i step to MRIQC and encountered some issues, please anyone experts in this community could help me?
Summary of what happened:
MRIQC version 24.1.0.dev0+g3fe90466.d20240417 was used to calculate the subject-level analysis, there were 56 subjects in total, and all subject folder generated the JOSN file, but almost half of them no figures and htmls generated. after checked the error, I found the wrong subjects were no info write into the sub-xxx_dwi.json file. I don’t know why this happened, cause all nifti file of each subjects are intact, include the json file. by the way i used heudoconv to convert all DICOM file into NIFTI format.
Command used (and if a helper script was used, a link to the helper script or the command generated):
I installed docker on windows, here is my code
$subids = $(cat H:\MRI_data\sublist.txt)
foreach($indexs in 0..55)
{
$proc_subs = $subids[$indexs]
docker run -it --rm `
-v F:\attention_data\Nift:/data:ro `
-v F:\attention_data\MRIQC:/out `
nipreps/mriqc:latest /data /out participant --participant_label $proc_subs
}
Version:
MRIQC version 24.1.0.dev0+g3fe90466.d20240417
Environment (Docker, Singularity / Apptainer, custom installation):
docker on windows wsl2
