Hi all
we are building a BIDS app whose inputs are:
-preprocessed resting state fMRI data (3D or 4D nii or nii.gz)
-brain (or a subset of it) mask (nii or nii.gz)
-TR
This input should be already present in the BIDS structure, either put there by the user itself, or read from the BIDS output of a preprocessing pipeline (i.e. FMRIPREP).
What’s the best way to tell our app to look for the appropriate input, or to ask the user to point to it?
thanks!
Daniele
There is no standard for this, but I would suggest the following as a good start
your_app <bids_root> <preproc_dir> <out_dir> <analysis_level>
Where:
-
bids_root
is the root of the BIDS dataset
-
preproc_dir
is the root of the BIDS derivatives folder (for example produced by FMRIPREP)
-
out_dir
is the output directory
-
analysis_level
is the processing stage (participant
, group
etc.)
You can also opt for making preproc_dir
optional and look for a specific folder in bids_root/derivatives
