Outputs

Unknown

The directory named unknown in the output directory is populated by NIFTI images that could not be identified. Files in this directory are generally named following this convention: sub-<label>[ses-<label>]_run-<label>_unknown.nii.gz, as shown in the example below (assuming that this study only had one session).

.misc

The .misc directory contains miscellaneous files that pertain to the image conversion process, such as log files (as shown below).

.bidsignore

The .bidsignore file is generated and intended for BIDS validation after data conversion. This file acts similarly to the .gitignore file - meaning files that should be ignored in the output BIDS directory should have their filenames written to this file. For example:

# .bidsignore file

unknown
.misc

The unknown and .misc directories are not BIDS valid directories and as such, would likely throw errors during BIDS validation.
