    1. "As much as I care what the phone call contained, I care more that my 401(k) is growing, because I have a child to put through college." Kim Alfano

      This seems to me as a classic example of 'the ends justify the means'.

    3. overall goals of this initiative are: Widening use of the ABCD dataset Enhancing rigor and reproducibility towards better predictive models Facilitating collaboration between clinical and computational researchers on normative and psychopathological neurodevelopment.

      overall goals

    4. Applications proposing prediction of outcomes within the baseline assessment (e.g., predictiing impulsivity scores at the baseline timepoint from neuroimaging measures) are encouraged to explicitly address validation strategies

      encouragement for validation

    5. Applications emphasizing the development of predictive models for identifying group/individual differences, with the overarching goal of predicting behavioral and clinical outcomes in future timepoints

      particular encouragement

    6. purpose of this FOA is to invite applications that involve research education on the use of ABCD data through meetings/workshops involving 1. Advanced seminars relevant to analysis of ABCD data, and 2. Hands on collaborative- or competition-style use of the ABCD dataset.

      purpose

    7. Two types of events are the focus of this initiative. The first includes competitive events where multiple research teams are pitted against each other towards a common challenge. The second includes collaborative events ranging from traditional workshops aimed at analysis-related training to hackathons or codeathons – where multiple participants gather to engage in collaborative computer programming.

    1. resting-state fMRI data were acquired using the whole brain single-shot multi-slice BOLD echo-planar imaging (EPI) sequence, with TR 2 s, TE 35 ms, flip angle 90°, voxel size 2 × 2 × 4 mm3, matrix 128 × 128, 32 contiguous transverse slices per volume, and 210 volumes per acquisition; resulting in total a resting-state acquisition of 7 min.

    2. esting-state fMRI data from University of Leuven in Belgium, available on the Autism Brain Imaging Data Exchange (http://fcon_1000.projects.nitrc.org/indi/abide)

      Sample 2

    1. Twenty‐six high‐functioning young adults who had previously received a clinical diagnosis of an ASD, and 26 age‐matched neurotypical controls

      Subjects

    1. All data generated and/or analyzed during this study are available from the corresponding author (BEY) on reasonable request.

      data accessibility statement

    1. 357 neurotypical (NT) males and 471 NT females from the 1000 Functional Connectome Project and 360 males with ASD and 403 NT males from the Autism Brain Imaging Data Exchange.

      subjects

    1. we included whether the subject was from the Temple or Geisinger cohort as a covariate, in order to minimize the impact of any differences between the two groups. We control for family wise error using Bonferroni correction (10 comparisons = critical p value of 0.05/10 = 0.005).

      statistical details

    2. Preprocessing steps included stripping non-brain material using the Brain Extraction Tool (BET) and motion correction, B0 unwarping, and slice time correction with FSL FEAT (fMRI Expert Analysis Tool) version 5.0.8. Images were normalized to 2 mm space via FLIRT and smoothed using a 5 mm Gaussian kernel. Four categorical regressors indicated whether the stimulus for each block was a face, place, food, or clock. Categorical regressors were boxcar functions at stimulus onset convolved with a double gamma function. Six estimated motion parameters were also included as nuisance regressors. Parameter estimate maps for each individual were then transformed into standardized t-statistic maps for each contrast (Faces, Places, Food, & Clocks).

      Analysis detail

    1. interaction between condition and group. Participant and item were included as random effects, and we fit an intercept for each participant and for each item, allowing the intercept to vary across individuals and items. To assess the importance of our predictors of interest, we performed likelihood ratio tests (LRTs) to test whether the model including a given predictor would provide a better fit to the data than a model without that term.

      stat details

    2. motion-corrected, realigned, normalized onto a common brain space (Montreal Neurological Institute, MNI, template), spatially smoothed using a Gaussian filter (full-width half-maximum = 8 mm kernel) and high-pass filtered (128 s)

    1. final dataset used in our analysis was composed of 397 males (mean age ± standard deviation, 16.29 ± 5.61 years) distributed along 19 datasets collected from 16 international sites

      Final dataset

    1. We investigated group differences in the relations of age with the four diffusion measures, averaged across all tracts, using ANOVA with factors for age, group and their interaction.

    2. Anatomical images were acquired using a 3D multiecho magnetization-prepared rf-spoiled rapid gradient-echo MEMPRAGE (T1 weighted) sequence with EPI based volumetric navigators for real time motion correction (Tisdall et al., 2012; van der Kouwe et al., 2008) TR = 2530 ms, Flip Angle = 7°, TEs = 1.74 ms/3.6 ms/5.46 ms/7.32 ms, iPAT = 2; FOV = 56 mm; 176 in-plane sagittal slices; voxel size = 1 mm3 isotropic; scan duration 6 m 12 s. DW-MRI scans were acquired using standard echo-planar imaging (TR = 8020 ms, TE = 83 ms, b = 700 s/mm2; 10 non-diffusion weighted T2 images acquired with b = 0; 60 diffusion directions; 128 × 128 matrix; 2 × 2 mm in-plane resolution; 64 axial oblique (AC-PC) slices; 2 mm slice thickness (0 mm gap); scan duration 9 m 47 s.

      scanning details

    1. High-resolution structural images were obtained using T1-weighted pulse sequences at 3T MR scanners at all sites, on Tim Trio at UCLA_1, USM, and Yale and on Allegra (Siemens, Erlangen, Germany) at NYU, and on a Signa (GE Medical Systems, Milwaukee, WI) at UM_1

      MRI acquisition details

    2. we chose the 20 youngest male participants with ASD and matched them as closely as possible on VIQ scores and cerebellar volumes (using left and right gray matter volume in mm3) to 20 male TD participants of similar age, as follows.

      subject selection

    1. we also hypothesized that such alterations will lead to differences in estimated functional connectivity in fMRI space compared to latent neural space
