Extract features from aligned signatures

Extract features from aligned signatures

Usage

extract_features_all(aligned, striae, resolution, tmpfile = NULL, ...)

Arguments

aligned

aligned signatures, result from sig_cms_max

striae

data frame with evaluated matching striae

resolution

micron per pixel resolution of scans

tmpfile

character consisting of the path to a temporary file. If not NULL, one line is appended to the file each time the function is executed.

...

passed on to extractor functions
