I have downloaded ABIDE-01 dataset that should supposed to be in BIDS format, but after validating the dataset with the BIDS validator BIDS_VALIDATOR.
But I am getting following two errors
- Error 1: [Code 55] JSON_SCHEMA_VALIDATION_ERROR
Click here for more information about this issue
Invalid JSON file. The file is not formatted according the schema.1 file
task-rest_bold.json 2.508 KB | application/json
Location:
ABIDEII-BNI_1/task-rest_bold.json
Reason:
Invalid JSON file. The file is not formatted according the schema.
Evidence:
.AcquisitionDuration should be number
- Error 2: [Code 212] PARTICIPANT_ID_PATTERN
Click here for more information about this issue
Participant_id column labels must consist of the pattern “sub-<subject_id>”.58 files
participants.tsv 89.661 KB |
Location:
ABIDEII-BNI_1/participants.tsv
Reason:
Participant_id column should be named as sub-<subject_id>.
Please guide me how to fix those two errors ?
My efforts
Error 1: To resolve this issue I guess that the “AcquisitionDuration” should be a number as currenty it has a value in the format “6:09” which I guess could be converted to a number such as 6.9.
Error 2 : To resolve this issue I have prefixed the subjects id with the “subject” keyword.
Now the errors are gone and only there are some warnings, but I have still this feeling that converting duration from “6:09” to a number 6.09 looks pretty wierd to me.
