All participants were scanned by a Siemens 3.0 Tesla Skyra scanner (Siemens, Germany). A twenty-channel standard head coil with foam pads is used to limit head movement. 3D T1-weighted MPRAGE with TR/TE/TI = 2,400/2.13/1100 ms, FOV = 256*256mm2, voxel size = 1.0*1.0*1.0mm3, slice thickness = 1 mm and number of slices = 192. 3D T2W-FLAIR with: TR/TE/TI = 5000/395/1800 ms, FOV = 256*256mm2, voxel size = 1.0*1.0*1.0mm3, slice thickness = 1 mm and number of slices = 192. Rest-fMRI with: TR/TE = 2000/30 ms, FOV = 224*224mm2, voxel size = 3.5*3.5*4.0mm3, slice thickness = 4 mm and number of slices = 32. These slices cover the entire brain and the MRI data were evaluated by two radiologists who did not know the clinical information.

We used high-resolution structural and diffusion MRI data from five healthy subjects (100307, 100408, 101915, 103414, 106016) of the Washington University, University of Minnesota, and Oxford University Human Connectome Project (WU- Minn HCP) consortium (39 (link)). The WU-Minn HCP scans were acquired on young healthy subjects (age 21–35) and represent the best neuroimaging data available for investigating the topography of the white matter in the human brain. The subjects were scanned on a customized Siemens 3.0 Tesla Skyra scanner using a 32-channel head coil and a customized gradient. The structural MRI data included T1-weighted and T2-weighted volumes acquired with the following parameters: T1-weighted: TE = 2.14 ms, TR = 2,400 ms, voxel size = 0.7 mm; T2-weighted: TE = 565 ms, TR = 3,200 ms, voxel size = 0.7 mm. The diffusion-weighted images were acquired using a single-shot 2D spin-echo multiband Echo Planar Imaging sequence with 90 gradient directions, 3 b-values (b1 = 1,000 s/mm2, b2 = 2,000 s/mm2, b3 = 3,000 s/mm2), 1.25 mm slice thickness and 1.25 mm image resolution (40 (link), 41 (link)). The diffusion-weighted images used in this study had been processed for intensity normalization, eddy-current, patient-motion and EPI distortion correction and co-registered to the anatomical scans (42 (link)–44 (link)).

All the images were obtained using a Siemens 3.0 Tesla Skyra scanner. For functional imaging in both task sessions, T2*‐weighted gradient‐echo echo‐planar imaging (EPI) sequences were used with the following parameters: time repetition = 2,500 ms, echo time = 25 ms, flip angle = 90°, field of view = 220 mm, and voxel dimension = 3.0 × 3.0 × 3.0 mm. Forty‐four contiguous slices with a thickness of 3 mm were acquired in an interleaved order. A high‐resolution anatomical T1‐weighted image (1 mm isotropic resolution) was also acquired for each participant.

Stimuli for the personalized affect fMRI task were approximately 3 s video clips of the mother’s adolescent or an unfamiliar adolescent displaying positive, aggressive, dysphoric or neutral behavior. Stimuli of the ‘own adolescent’ condition were derived from the video recording of the parent–child interaction task described above. The video clips were selected by a trained staff member and then validated by a second rater; if there were discrepancies, they would discuss it to reach a consensus. The unfamiliar adolescents were actors, matched on sex to the target adolescent, discussing topics typical to the mother–adolescent interaction task. All clips had video and audio and session runners ensured that sound was working in the scanner. There were 15 trials of each condition, which led to 120 trials in total (15 × 4 emotions × own and unfamiliar adolescent). Trials were approximately 3 s long and interspersed with 1 s rest (fixation cross).
All scans were acquired using a Siemens Skyra 3.0 Tesla scanner at the Lewis Center for Neuroimaging at the University of Oregon. Scan specifications were as follows: 2 mm isometric voxels, multiband acceleration factor = 3, in plane acceleration factor = 2, TR = 2000 ms, TE = 25 ms, 72 slices of 208 × 208 mm.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
