Fixes and Updates

August 15, 2018

KSADS data on LORIS (Diagnosis_KSADS) has been updated. Fields are now named after the item name, rather than numerically. Data will be uploaded to COINS next week.

ANNOUNCEMENTS

  • Users can now use the HBN biobank forum to ask questions and discuss topics related to the HBN dataset. Please note that users must use their Google account to request access to the forum, and that all posts need to be approved before being made public.

PROTOCOL ADDITIONS

PROTOCOL FIXES

  • Scan parameters on the MRI protocol page have been updated to reflect changes to the protocol announced on Jan. 22, 2018.
    RUBIC Scan Parameters
    CBIC Scan Parameters

DATA ADDITIONS

  • Phenotypic Data
    • Sibling Matching Data
    • Activities of Daily Living (ADL) questions added to developmental history section of intake interview (Instrument in COINS/LORIS: PreInt_DevHx)

July 18, 2018

Phenotypic data for release 4.0 (n = 1551) are now available on COINS and LORIS. Neuroimaging data will be available later this month.

Jan 31, 2018

The following updates are included in Release 3.0:

PROTOCOL ADDITIONS

  • Citigroup Biomedical Imaging Center (CBIC) at Weill Cornell Medical College- We are pleased to announce the addition of CBIC as a scan site for the Healthy Brain Network. Located in the Upper East Side of Manhattan, New York, this center will serve as a major scan site with coverage of participants from the Manhattan and nearby areas to the east (e.g., Brooklyn).
  • New phenotypic assessments

PROTOCOL DISCONTINUATION

PROTOCOL IMPROVEMENTS

  • Integration of Prospective Motion Correction (In Progress)- The most commonly cited challenge for the collection of data from children and hyperkinetic clinical populations is head motion. As part of an effort to minimize the impact of head motion on the collection of data from HBN participants, we have begun the process of adding prospective motion correction to our protocols. Specifically, the Align sequence used by the NIH ABCD Study was added at the CBIC site for the T1 and T2-SPACE images. For the purposes of maintaining continuity, and facilitating comparison of results, we have maintained acquisition of the initial T1 image at CBIC as well. Addition of the T1 at RUBIC is pending a port of the sequence to VB19A.

    File identifiers:

    • T1 – HCP-based Sequence (no VNav)
    • T1 – ALIGN (VNav with and without surface coil intensity correction)
    • T2–SPACE HCP-based Sequence (no VNav)
    • T2-SPACE – ALIGN (VNav with and without surface coil intensity correction)

DATA ADDITIONS

  • Voice transcription data. Release 3 data include transcriptions of voice recordings taken after the MRI scan, where participants described the plot of The Present and their reaction to the film. These files (.txt, n = 232) will be available in the Document Repository on LORIS and under Study Docs in COINS.

DATA FIXES

  • Diagnostic Data. Users should note that the assessment "ConsensusDx" has been changed to "Diagnosis_ClinicianConsensus" in order to address confusion with finding participant diagnostic information. In addition, diagnostic data from the computerized Kiddie Schedule for Affective Disorders and Schizophrenia (KSADS) will be available as "Diagnosis_KSADS," providing another option for diagnostic data. While for most participants, diagnoses will be consistent between the clinician consensus and the KSADS results (the clinician consensus diagnosis is determined from the KSADS results, as well as from other assessments), the clinician consensus diagnosis data include a wider range of diagnoses, including autism and learning disorders.

DISTRIBUTION NOTE

  • S3 Directory Structure. HBN neuroimaging data are now available in both compressed (.tar.gz) and uncompressed format in S3, under the directories fcp-indi/data/Archives/HBN and fcp-indi/data/Projects/HBN, respectively. Data will still be available for direct download on the neuroimaging downloads page, but only for compressed files.

Jan. 22, 2018

We have changed the order of scans in the HBN protocol to maximize yield. Scan types are now classified as minimal, core and extended, to reflect priority. These changes will be reflected in Release 4.0. Below we depict the change in protocol:

Release 3 - Changes in MRI Protocol

Dec. 08, 2017

EEG ReadMe files that describe event triggers and behavioral data labels have been added to the Neuroimaging Data Access page.

Dec. 06, 2017

T2-Space sequence parameters were updated in November, 2017 due to suboptimal bandwidth parameter setting that adversely affected the TE and resulted in substantially reduced T2 contrast. All the T2 images collected from Rutgers (Site RU) in both Release 1 and Release 2 are affected. The following table shows changed T2 parameters before and after the update.

Before Update After Update
Bandwidth 240 744
Echo Train Duration 1783 1243
Turbo Factor Off 195
Echo Spacing 6.3ms 3.5ms
