|
||
In addition to the data, the ABCC read-the-docs provides helpful links to how to use, process, and analyze ABCD data. The documentation guide below will take users to different sections for more information. | ||
|
||
## 2. Background | ||
|
||
As a community share, the ABCC enables researchers to access **available derivatives** and share their **own derivatives.**. The ABCD-BIDS datasets are continually updated as new ABCD releases become available. A list of currently available datasets are provided below. | ||
|
||
1. `BIDS inputs` The input DICOM data to this [BIDS version 1.2.0](https://www.nature.com/articles/sdata201644) data collection were retrieved from the [NIMH Data Archive (NDA) share of ABCD fast-track data](https://nda.nih.gov/edit_collection.html?id=2573) and were last accessed on May 1, 2019. BIDS input data were converted from DICOMs using [Dcm2Bids](https://github.com/cbedetti/Dcm2Bids). | ||
2. `abcd-hcp-pipeline` BIDS derivatives data were derived from the [DCAN Labs ABCD-BIDS MRI processing pipeline](https://doi.org/10.5281/zenodo.2587210) which outputs [Human Connectome Project (HCP) Minimal Preprocessing Pipelines-style data](https://doi.org/10.1016/j.neuroimage.2013.04.127) in both volume and surface spaces. This collection is independent from ABCD Data Collection 2573. Users may access ABCD DICOM files via the ABCD fast-track imaging data release in Collection 2573. | ||
3. `abcd-task-hcp-pipeline` | ||
4. `freesurfer-5.3.0-HCP` segmentation statistics and surface morphometrics from the FreeSurfer stage within the [DCAN Labs ABCD-BIDS MRI processing pipeline](https://doi.org/10.5281/zenodo.2587210) are provided here. | ||
5. `QSIPrep` | ||
6. `fMRIPrep` | ||

- The timeseries data has been reprocessed with an updated version of the abcd-hcp-pipeline (v1.0.3) with improved bandpass filtering to the BOLD data. The new implementation zero pads the BOLD data prior to filtering to minimize distortions at the beginning and ending timepoints. It's important to note that this is not a bug, but rather an improvement. This release does not invalidate previous results, it reduces variance towards the beginning and end of the time-series data. In the previous release, those frames are labeled as "outliers" and discarded according to the provided mask. Using these updated timeseries users should be able to include more data in their analyses. (TODO: Provide specific derivatives filenames) | ||

- New version of [QSIPrep](https://qsiprep.readthedocs.io/en/stable/)- year 1 derivatives. | ||
- There was in issue for some subjects in distortion correction that resulted in very inaccurate distortion correction results. This was due to TOPUP being given a denoised b=0 image from the DWI series and a raw b=0 image in the opposite phase encoding direction (taken from the image in the fmap/ directory). We updated QSIPrep to use the unprocessed b=0 images in both phase encoding directions, which resulted in TOPUP performing as expected. | ||
- New version of [QSIPrep](https://qsiprep.readthedocs.io/en/stable/) v0.14.2 year 1 derivatives. | ||

The bug affected a subset of subjects, but it is worth suggesting that anyone using the initial data re-calculate their analysis using the updated version. | ||

(TODO: Edit this section @Feczko) | ||
- New version of [fMRIPrep](https://fmriprep.org/) 23.x.x year 1 derivatives. Special thanks to Thomas Madison, etc. | ||
- Improved distortion correction | ||
- Improved bold projection to surface | ||
- New CIFTI outputs | ||
- T2w in T1w volume space | ||
|
||
- Change to participants.tsv format (TODO: Anders link to recomendations section) | ||

- New version of [fMRIPrep](https://fmriprep.org/) 23.0.0rc0 year 1 derivatives. For specifics on what has changed since fMRIprep v20.2.0 and fMRIprep 23.0.0rc0, see the change log for the software [here](https://fmriprep.org/en/stable/changes.html). | ||
