Data not openly available. Used BIDS-ified dataset on Elm.
## BIDS validation fixes
Ran the following scripts to fix errors:
1. `1_create_dataset_description.py`
- `1_create_dataset_description.py`
- creates `dataset_description.json` at the root directory with minimal information
- BIDS version used is unknown, so specified latest version (see [discussion]( https://neurostars.org/t/what-bids-version-to-use-for-legacy-dataset/25619))
- fixes BIDS validation error `code: 57 DATASET_DESCRIPTION_JSON_MISSING`

2. `2_create_task-rest_bold.py`
- `2_create_task-rest_bold.py`
- creates `task-rest_bold.json` at the root directory, detailing bold task
- fixes BIDS validation error `code: 50 TASK_NAME_MUST_DEFINE`

3. `3_create_bidsignore.sh`
- `3_create_bidsignore.sh`
- creates `.bidsignore` at the root and adds `*T1w_cropped.nii` to ignore these files, which are not needed
- fixes BIDS validation error `code: 1 - NOT_INCLUDED`
- TODO: check this also fixes error `code: 63 - SESSION_VALUE_CONTAINS_ILLEGAL_CHARACTER`, it should do

3. `4_correct_slice_timing.py`
- `4_correct_slice_timing.py`
- halves the slice timing for sub-109S4594 (ses-20160502), which appears to be doubled (see [discussion](https://neurostars.org/t/help-with-bids-errors-66-and-75-in-legacy-dataset/25625))
- fixes BIDS validation error `code: 66 SLICETIMING_VALUES_GREATOR_THAN_REPETITION_TIME`
