Hello everyone!
I’m new to BIDS formatting and am encountering an issue while trying to validate my resting-state fMRI data. When I run my dataset through the online BIDS Validator, I’m getting the following error:
error: SIDECAR_KEY_REQUIRED (TaskName)
with the following structure:
- Path: BIDS > sub-001 > func
- Files:
- sub-001_task-rest_bold.json
- sub-001_task-rest_bold.nii
Can someone please help me understand:
1.How can I fix this?
2. My data is resting-state fMRI, how should I define TASKNAME?
3. If there are two runs, can I named them with 'sub-001_task-rest_run1_bold.nii/.json ’ and 'sub-001_task-rest_run2_bold.nii/.json ’
