[GRASS-user] i.histo.match error

[Luís Mário Ribeiro]

Hello list,

Changed the names of 2 files to not have any "." and rerun histo.match. A
different error showed. 
I copy below the output window contents. It refers to an error in " r.stats"
(ERROR: Sorry, <fs> is not a valid parameter)
Does anyone know what I'm doing wrong?

i.histo.match --overwrite
input=2030312007052_3 at histomatch,2030322007052_3 at histomatch max=1000
Description:
 Generates area statistics for raster map layers.
Keywords:
 raster, statistics
Usage:
 r.stats [-1AacplgxrnNCi] input=name[,name,...]
[output=name]
   [separator=character] [nv=string] [nsteps=value]
[--overwrite]
   [--verbose] [--quiet]
Flags:
  -1   One cell (range) per line
  -A   Print averaged values instead of intervals
  -a   Print area totals
  -c   Print cell counts
  -p   Print APPROXIMATE percents (total percent may not be
100%)
  -l   Print category labels
  -g   Print grid coordinates (east and north)
  -x   Print x and y (column and row)
  -r   Print raw indexes of fp ranges (fp maps only)
  -n   Suppress reporting of any NULLs
  -N   Suppress reporting of NULLs when all values are NULL
  -C   Report for cats fp ranges (fp maps only)
  -i   Read fp map as integer (use map's quant rules)
 --o   Allow output files to overwrite existing files
 --v   Verbose module output
 --q   Quiet module output
Parameters:
      input   Name of input raster map(s)
     output   Name for output file (if omitted or "-" output
to stdout)
  separator   Field separator
               Special characters: newline, space, comma,
tab
              default: space
         nv   String representing no data cell value
              default: *
     nsteps   Number of fp subranges to collect stats from
              default: 255

 [>]Good morning and thanks... Will try changing the "." (which was added by
Grass when performing i.topo.corr).
Best regards, luis

I guess (not sure though) it is the same error once pointed to me by Luca
Delucchi:  the "." in the input raster map names is not allowed :-(.

You need to rename them...  Maybe a quick test first to be sure.  Shrink
your region and test.  Be sure you have beforehand a MASK or else which you
use to set the computational region.  Or, export your current working region
in a vector map?  (<-- v.in.region).

Hope it works, Nikos
