Hi @Hongxiu_Jiang,
In the future. please format computer text (like the JSON contents) as code using the </> button in the text editor. You can see I did that for you this time.
It looks like you are missing the TaskName field from your BOLD JSONS. Something like "TaskName": "Movie Cloudy" would suffice. I would also fix the session naming (change sub-C010session2 to sub-C010/ses-2/ and fix the filenames accordingly). Also, I imagine you want the task label just to be task-MovieCloudy, and instead have the acq-fmri3mmiso and dir-AP labels, since that information is not about the task.
IntendedFor is a fmap JSON field that maps to the BOLD file you want to apply it to, relative to the inside of the subject folder, for example (after applying the name changes I suggested):
"IntendedFor": ["ses-2/func/sub-C010_ses-2_task-MovieCloudy_acq-fmri3mmiso_dir-AP_run-1_echo-1_bold.nii.gz", ADD_OTHERS_HERE]
For B0FieldSource/Identifier, in the fmap json you give the fmap a name, such as
"B0FieldIdentifier": "fmap_for_cloudy_run1"
and then in any BOLD json you want to apply that to, put in
"B0FieldSource": "fmap_for_cloudy_run1"
The B0FieldSource/Identifier method takes precedence over IntendedFor if both are specified.
Best,
Steven
