| fiber.lengths {GoodFibes} | R Documentation |
Calculated the length of smoothed muscle fibers
Description
Determines the length of reconstructed and smoothed muscle fibers. Fibers are smoothed using splines::ns and then oversampled (length.out). The sum of all straight line segments on the smoothed paths is taken as the overall fiber length
Usage
fiber.lengths(fib.list, res = NULL, df = 2, length.out = 500)
Arguments
fib.list |
A list of fibers containing $fiber.points. Produced by good.fibes or the various cleaning functions (quality check, fuse.fibers, check.overlap) |
res |
The resolution of the isometric voxels (i.e., the distance between images). Should be given as a linear measure (e.g., mm, um) |
df |
The degrees of freedom passed to splines2::nsp. A df = 1 produces a straight fiber, while values >1 allow fibers to curve. |
length.out |
The number of straight line segments that the smoothed curve will be divided into for calculation of length |
Value
A vector with fiber lengths
