fs.tracts.lengths R Documentation
Get the number of points of each tract.
Description
Returns one integer per tract, the number of points it consists
of. The coordinates of tract i are the rows
(cumsum(c(1, lengths))[i]):(cumsum(lengths)[i]) of
fs.tracts.coords().
Usage
fs.tracts.lengths(tracts)
Arguments
tracts
an fs.tracts instance, as returned in the tracks
entry of read.dti.tck or read.dti.trk.
Value
integer vector with one entry per tract.

## Not run:
tck <- read.dti.tck("brain.tck");
lengths <- fs.tracts.lengths(tck$tracks);
