R Documentation

Set Minimum/Maximum Values for NIfTI data

Description

Rescales image cal_max and cal_min slots to be the max and min, respectively, of an object of class nifti, with na.rm = TRUE. This is so that when images are rendered/written, the values correspond to those in the array (stored in .Data slot) are plotted on correct greyscale and no error is given by writeNIfTI.

Usage

calibrateImage(img, infok = TRUE)

cal_img(img, infok = TRUE)

Arguments

`img`	is a `nifti` object.
`infok`	is a logical value whether or not `Inf` and `-Inf` are acceptable (default = `TRUE`). If `FALSE` and max or min is infinity, then `cal_min` or `cal_max` is set to infinity (negative or positive), respectively.
