neuroCombatFromTraining.Rd[UNDER DEVELOPMENT] neuroCombat harmonization using parameters estimated from a training dataset. Estimated parameters are applied to a new dataset, assuming scanners/batches in the new dataset were also present in the training dataset.
neuroCombatFromTraining(dat, batch, estimates, mod = NULL, verbose = TRUE)| dat | Numeric matrix with imaging features as rows, and scans/images as columns.  | 
    
|---|---|
| batch | Numeric or character vector specifying the batch/scanner 
variable needed for harmonization. Length must be equal to the 
number of columns in   | 
    
| estimates | Prior neuroCombat estimates to be applied onto
the new dataset. Usually obtained from the output of
  | 
    
| mod | Optional model matrix for outcome of interest and other covariates besides batch/scanner.  | 
    
| verbose | Should progress messages be printed? TRUE by default.  | 
    
A named list of length 2. The first element (dat.combat)
    contains the harmonized data. The second element (estimates) contains
    estimates and other parameters used during harmonization.
