Getting Setup with Neurodesk

For more information on getting set up with a Neurodesk environment, see here

FreeSurfer Example using module load (e.g. on an HPC)

Download data:


osf -p bt4ez fetch osfstorage/TOMCAT_DIB/sub-01/ses-01_7T/anat/sub-01_ses-01_7T_T1w_defaced.nii.gz sub-01_ses-01_7T_T1w_defaced.nii.gz

Setup FreeSurfer:


ml freesurfer/7.3.2
export SUBJECTS_DIR=$PWD/freesurfer-output
mkdir $SUBJECTS_DIR
export SINGULARITYENV_SUBJECTS_DIR=$SUBJECTS_DIR
export APPTAINERENV_SUBJECTS_DIR=$SUBJECTS_DIR

Run Recon all pipeline:


recon-all -subject test-subject -i sub-01_ses-01_7T_T1w_defaced.nii.gz -all

When using Freesurfer >8.0.0:


export FS_ALLOW_DEEP=1
export APPTAINERENV_FS_ALLOW_DEEP=$FS_ALLOW_DEEP
export SINGULARITYENV_FS_ALLOW_DEEP=$FS_ALLOW_DEEP

When running on a GPU, make sure to check if this is set:


export neurodesk_singularity_opts='--nv'

Download demo data

Open a terminal and run:


pip install osfclient
osf -p bt4ez fetch TOMCAT_DIB/sub-01/ses-01_7T/anat/sub-01_ses-01_7T_T1w_defaced.nii.gz /neurodesktop-storage/sub-01_ses-01_7T_T1w_defaced.nii.gz
