Inputs a MINC file or RMINC output and identifies peak voxels (given some constraints) within
mincFindPeaks(inputStats, column = 1, direction = "both", minDistance = NA, threshold = NA, posThreshold = NA, negThreshold = NA)
| inputStats | Either an RMINC object or a filename from which peaks are to be determined. |
|---|---|
| column | If an RMINC object then the column name or number |
| direction | "both", "pos" for positive peaks only, or "neg" for negative peaks only |
| minDistance | minimum distance, in mm, between peaks |
| threshold | threshold above which to consider peaks |
| posThreshold | positive threshold (overrides threshold if both are given) |
| negThreshold | negative threshold (overrides threshold if both are given) |
The set of peaks as a matrix. The matrix is of dimensions ntags x 7; the first three columns correspond to the first three dimensions in the same coordinates as used by mincArray; the next three columns are the x, y, and z coordinates in world space, and the 7th column is the value at that location.
Provides an interface to find_peaks, a command line program that comes with the MINC library.
