This code is used to identify matched controls, as required to test an implementation of the RISH harmonization method described in Karayumak et al., 2019. We use data from the SPINS study, and match 5 target sites (CMP, MRC, MRP, ZHH, ZHP) to the reference site (CMH).
In all cases, we aim to identify the gold-standard of n=20 matched ‘healthy control’ participants (or at least, the recommended n=16-18), on the basis of sex, age,IQ (here, established by WTAR), and handedness.

Special notes
Because we could not match on the basis of handedness (established by EHI ≥ .5) for another site, we did not attempt to match on the basis of handedness here (nor will we for any other target site).
