Error using qsiprep: "'dataset_description.json' is missing from project root. "

ldaumail · November 23, 2024, 12:24am

Continuing the discussion from Dataset_description.json missing from project root, file exists in project root:

Summary of what happened:

I am trying to run qsiprep on a BIDS validated dataset (with a few warnings but they don’t seem relevant to the issue I am having here).

I checked and /opt/conda directory does not exist on my laptop. It may be in the container?
On my end, I use VSCode Version: 1.95.2 (Universal)
I created a /.conda virtual environment with Python 3.9.20
And my laptop is Apple M3 Pro with Mac OS Sonoma 14.7.1

Command used (and if a helper script was used, a link to the helper script or the command generated):

import os
import os.path as op
# 
# qsiprep (preprocessing)
version = "latest"
bids_dir = op.join(op.expanduser('~'), 'Documents/research/ampb_mt_tractometry_analysis/ampb')
output_dir = op.join(op.expanduser('~'), 'Documents/research/ampb_mt_tractometry_analysis/ampb/derivatives')

participants = [f for f in os.listdir(bids_dir) if f not in {".DS_Store", "dataset_description.json", "code","derivatives"}]
participants_cleaned = [f.replace("sub-", "") for f in participants]
print(participants_cleaned)

for participant in participants_cleaned:
    cmd = f"docker run --rm " \
        f"--volume {bids_dir} " \
        f"--volume {output_dir} " \
        f"--volume $FREESURFER_HOME/license.txt " \
        f"pennlinc/qsiprep:{version} " \
        f"--skip-bids-validation " \
        f"{bids_dir} {output_dir} " \
        f"participant --participant-label {participant} " \
        f"--ignore fieldmaps " \
        f"--output-resolution 1.5 " \
        f"--fs-license-file $FREESURFER_HOME/license.txt " 

    os.system(cmd)

Version:

1.0.0rc1

Environment (Docker, Singularity / Apptainer, custom installation):

I am using Docker, I installed Docker desktop from the website
Docker version 27.3.1, build ce12230
I then pulled pennlinc/qsiprep:latest from DockerHub.

Hi @ldaumail,

What are the contents of your dataset_description.json?

Best,

Hi @ldaumail,

Can you fix the dataset to be BIDS valid by removing the subjects folder? Also how were these data converted to BIDS? And what vendor did they come from. That is a worrying amount of warnings. Can you also try adding the -ti flag to the docker preamble? And specify a work dir (-w qsiprep flag).

Will you be eventually working working on a compute cluster? If so I recommend troubleshooting there. Some tools used in qsiprep rely on tensorflow versions that do not work on Apple silicon.

Best,
Steven

Hi @Steven,

Thanks for your suggestions.

I added -ti and a work directory. Now this is the error I am getting:
"
the input device is not a TTY
"

I will look into the BIDS data formatting, I did not convert this raw data into bids myself.

Best,
