#### 3. DBP Motion censoring
8282

83-
Our motion censoring procedure is used for performing the standard pre-processing and for the final construction of parcellated timeseries. For standard pre-processing, data are labeled as "bad" frames if they exceed an FD threshold of 0.3 mm. Such "bad" frames are removed when demeaning and detrending, and betas for the denoising are calculated using only the "good" frames. For band-pass filtering, interpolation is used initially to replace the "bad" frames and the residuals are extracted from the denoising GLM. In such a way, standard pre-processing of the timeseries only uses the "good" data but avoids potential aliasing due to missing timepoints. After motion censoring, timepoints are further censored using an outlier detection approach. Both a mask including outlier detection and a mask without outlier detection are created. [These masks](https://collection3165.readthedocs.io/en/stable/derivatives/#7-motion-mat-file) are HDF5 compatible .MAT files, which contain temporal masks from 0 ("No censoring") to 0.5 FD thresholds in steps of 0.01.

The ABCC houses a community-shared and continually updated ABCD neuroimaging dataset available under Brain Imaging Data Structure (BIDS) standards. Source data are converted to BIDS from the [NIMH Data Archive (NDA) share of ABCD fast-track data](https://nda.nih.gov/edit_collection.html?id=2573). Only data that passed the Data Analysis Imaging Center (DAIC) quality control are included.

Currently, the ABCD-BIDS Community Collection (ABCC) from the Developmental Cognition and Neuroimaging (DCAN) Labs contains a regularly updated dataset of ABCD Brain Imaging Data Structure (BIDS) version 1.2.0 pipeline inputs and derivatives. Source data are currently comprised of all the ABCD Study participants baseline year 1 arm 1 DICOM imaging data that passed initial acquisition quality control from the ABCD Data Analysis and Informatics Center (DAIC) and were processed by DCAN Labs.

Source data are currently comprised of all the ABCD Study participants baseline year 1 arm 1 DICOM imaging data that passed initial acquisition quality control from the ABCD Data Analysis and Informatics Center (DAIC) and were processed by DCAN Labs. Per task, the first two bold runs that passed QC were pulled and converted to BIDS.
