SYNOPSIS

i.signatures
i.signatures --help
i.signatures [-p] [type=name] format=name [mapset=name[,name,...]] [remove=name[,name,...]] [rename=from,to[,from,to,...]] [copy=from,to[,from,to,...]] [--help] [--verbose] [--quiet] [--ui]

Flags:

-p: Print signature files
--help: Print usage summary
--verbose: Verbose module output
--quiet: Quiet module output
--ui: Force launching GUI dialog

Parameters:

type=name: Type of signature file
Options: sig, sigset, libsvm
format=name [required]: Output format
Options: plain, json
Default: plain
plain: Plain text output
json: JSON (JavaScript Object Notation)
mapset=name[,name,...]: Name of mapset to list
Default: current search path
remove=name[,name,...]: Name of file(s) to remove
rename=from,to[,from,to,...]: Name of file to rename
copy=from,to[,from,to,...]: Name of file to copy

DESCRIPTION

i.signatures module allows to manage signature files:

"sig" – generated by i.gensig for i.maxlik
"sigset" – generated by i.gensigset for i.smap

The module can perform multiple actions per run. The order of execution is "copy", "remove", "rename". When the print flag is specified without specifying any type of signature files, it would print all signatures grouped by type.

NOTES

By default the module will list signature files from all mapsets in the current search path. It is possible to limit listing only to a single mapset by providing the "mapset" option. The mapset can be also not listed in the current search path.
Actions "remove" and "rename" operate only on the current mapset (although accept fully qualified names). The "copy" action will accept a signature file name from any mapset as its first argument (source file to copy).

EXAMPLES

Print names of all signature files:

i.signatures -p

Print only signature files of certain type as a JSON:

i.signatures -p type=sigset format=json

Delete signature file called "foo" of type "sig" (i.gensig / i.maxlik).

i.signatures remove=foo type=sig

Copy signature file "bar" from mapset "baz" to current mapset

i.signatures copy=bar@baz,best_version type=sigset
