.SS Parameters:
.IP "\fBmap\fR=\fIname\fR" 4m
.br
Name of input raster map

.SH DESCRIPTION
\fIr.li.mps\fR 
(mean patch size) calculates the mean size of the patches in the sampling area as:
.br
with:
.RS
.IP
\fBA\fR:sampling area size without null cells
.IP
\fBNpatch\fR: number of patches
.br
.RE
.SH EXAMPLES
To calculate mean path size index on map my_map, using
my_conf configuration file and saving results in
my_out file run:
.br
\fC
.DS
.br
r.li.mps map=my_map conf=my_conf output=my_out
.br
.DE
\fR
.SH NOTES
Do not use absolute path names for output files. They are raster if
moving window disposition was selected, otherwise they are in
~/.r.li/output folder.
.br
If input raster is full of null values r.li.mps returns 0.
.br
If you want to have null values instead run 
.br
\fC
.DS
.br
r.null setnull=0 map=my_map
.br
.DE
\fR
after index calculation.
