Structural neuroimaging data collected as part of the Neuroscience in Psychiatry Network is shared as it and in line with the data used in prior publication (see for example Whitaker, Vertes et al. 2016). All structural scans were acquired using the MPM sequence implemented on three identical 3T whole-body MRI systems (Magnetom TIM Trio; VB17 software version; Siemens Healthcare): two located in Cambridge and one located in London. Between-site reliability and tolerability of all MRI procedures were satisfactorily assessed by a pilot study of five healthy volunteers each scanned for ∼25 min at each site. The between-site bias was less than 3% and the between-site coefficient of variation was less than 8% for both longitudinal relaxation rate (R1) and MT parameters. R1 and MT were quantified in Matlab (The MathWorks, Inc.) using SPM8 (www.fil.ion.ucl.ac.uk/spm) and custom tools implemented via the HMRI toolbox (https://hmri-group.github.io/hMRI-toolbox/). To enable easy usage we chose to share quantitative and semi-quantitative R1, R2*, MT and PD maps.
