title: Robust group- but limited individual-level (longitudinal) reliability and insights into cross-phases response prediction of conditioned fear

description: Here we follow the call to target measurement reliability as a key prerequisite for individual-level predictions in translational neuroscience by investigating i) longitudinal reliability at the individual and ii) group level, iii) cross-sectional reliability and iv) response predictability across experimental phases. 120 individuals performed a fear conditioning paradigm twice six month apart. Analyses of skin conductance responses, fear ratings and BOLD-fMRI with different data transformations and included numbers of trials were conducted. While longitudinal reliability was generally poor to moderate at the individual level, it was good for acquisition but not extinction at the group-level. Cross-sectional reliability was satisfactory. Higher responding in preceding phases predicted higher responding in subsequent experimental phases at a weak to moderate level depending on data specifications. In sum, the results suggest the feasibility of individual-level predictions for (very) short time intervals (e.g., cross-phases) while predictions for longer time intervals may be problematic.

title: Unbiased simulation of Alanine Dipeptide in gas phase

description: 87 microsecond long unbiased Molecular Dynamics (MD) trajectory of alanine dipeptide in gas phase (traj_comp.xtc). Temperature = 300 K. Force Field: AMBER99SB-ILDN. There are 30+ back and forth transitions between the C_7eq and the C_7ax state. Simulations were performed using GROMACS 2021.4. The .tpr file is provided for reproduction. Details of the simulation parameters are accessible from the md.log file. The phi and psi torsion angles and the internal energy is printed in the COLVAR file at 2 ps interval. Alanine dipeptide is often used as a model system to test new simulation methods. We hope that sharing our long unbiased trajectory will help other research groups to compare the accuracy of the results obtained from new methods. This trajectory was generated as a part of our recent publication below. Please cite the following paper when using this trajectory: 1.
