[GRASS-user] r.fuzzy.system: specifying raster file?

GRASS GRASS user
1

Hi,

I'm trying to run the r.fuzzy.system module - have created the map and rules
files, but can't seem to find where to specify the input raster file in the
r.fuzzy.system gui window. I can select the .map, and .rul file, but there
doesn't seem to be a field for the input raster file. As indicated on
running the extenion:
ERROR: Raster map <mti> not found

Also tried adding 'input=filename' and running from the command line but:
Sorry, <input> is not a valid parameter

I guess that that the input raster file needs to be specified in the .map
file, but I'd be grateful for any advice on the syntax needed to specify. My
flood.map file contains the following:

%mti
$ low {right; -1,3; sshaped; 0; 1}
$ moderate-low {both; -1,3,4,5; sshaped; 0; 1}
$ moderate-high {both; 4,5,11,14; sshaped; 0; 1}
$ high {left; 11,14; sshaped; 0; 1}

My rules file:
$ low {mti = low}
$ moderate-low {mti = moderate-low}
$ moderate-high {mti = moderate-high}
$ high {mti = high}

Replacing '%mti' with '%actualfilename' gets me a bit further, but I also
need to include the definition of the output file in the .map file:

ERROR: No defininition for output map: <watershed_flood_fuzzy> in map file

The related source code snippet is (I think):

map_parser.c:
        if (*buf == '%') {

            fgetpos(fd, &position);

            sscanf(buf, "%[^\n]", map);
            char_strip(map, '%');
            G_strip(map);
            mapset = (STRING) G_find_raster2(map, "");

So the word after % might be taken as map name as seen for example in
http://trac.osgeo.org/grass/browser/grass-addons/grass7/raster/r.fuzzy/r.fuzzy.system/flood.map

Perhaps the author can help to explain/confirm?

Although I am not the author of that module, I can confirm that the input raster files are specified in the .map file as explained in the example.

Hi,

I am experiencing a similar problem. I have followed the steps as in the
example, making sure all the maps are in the search path but
r.fuzzy.system keeps reporting an error regardless of the map specified:

My input map definition in the .map file:

%elevation
$nlow{left; -3,-2; linear; 0; 1}
$scar{both; -3,-2,0,2; linear; 0; 1}
$nhigh{right;0,2; linear; 0; 1}

Reported Error:

"Illegal filename. Character <

not allowed.

ERROR: Raster map
<elevation

not found"

I have also tried to specify the mapset using "@" as explained in the
example, still the same error regardless of the map (and respective
mapset)

My input map definition in the .map file:

%elevation@PERMANENT
$nlow{left; -3,-2; linear; 0; 1}
$scar{both; -3,-2,0,2; linear; 0; 1}
$nhigh{right;0,2; linear; 0; 1}

Reported Error:

"Illegal filename. Character <

not allowed.

ERROR: Raster map
&lt;
elevation@PERMANENT
&gt;
not found"

I will be grateful for any advice in finding out the source of this error
and how to rectify it.

Beatrice.

Hi Beatrice,

I traced down your problem(s) with your files for r.fuzzy.system. First, thank you for the minimal examples. That were great for tracing the problem.
So there were three problems:

  1. you defined two output levels (res1 and res2) in your .MAP file but you used different levels in your .RUL file (rul1 and rul2)

  2. you did not include the shape factor (e.g. “linear”) in the definiton of your output classes

  3. And the real problem that caused all your problems were the line endings. You’re probably working on Windows and the Windows text editor you used for creating your files have by default a different definition of a “new line”. This is different to Linux line endings. Common simple texteditors do not show which line endings are in use so it is really difficult for a user to realize that there are different line endings (I had the same problems some months/years ago). So what I did: I am using now TextWrangler on my Mac as text editor of my choice. This program and probably many others (also for Windows) allow to change the definition of the line endings to Unix-like “newlines”. Just change that and than your fuzzy system will work smoothly (tested with GRASS6.5 so there is no need to run r.fuzzy.system in GRASS7)…

Hi again…

which version of GRASS are you using at the moment? I know that I had some problems with the 6.X version, thus all my work is done with GRASS 7.0. So maybe you can try it with GRASS 7.0 and see if that already solves your problem.

Anyway I can have a look at your minimal example you provided next week on my GRASS 7 machine.

Hi Johannes,

Thank you very much for your help.

The problem still persist. I did work in one mapset with all the input maps in this mapset, simple map names and only two input maps. The raster maps “B3/B4/B7” were imported by r.in.gdal and “ndii” is an index of these other maps computed by r.mapcalc. My .map file is similar to the one I sent to you with relevant input map names and fuzzy sets definitions.

These are the maps in my mapset:

g.list rast

raster files available in mapset :
B3 B4 B7 ndii

Same error message for a different input map

I am attaching very simplified .map and .rul files that use GRASS North Carolina dataset in the landsat mapset. I use file names as they are here but I tried with simple map names and got the same error message.

Hi,

thank you for the information. From a first view, I don’t see any major errors in you files.

However, to trace your problem I’d suggest to work only in one mapset and have all maps that are specified in the map-file in that mapset. Than you can also skip the trailing “@PERMANENT”. Furthermore I’d suggest to use only three or even only two maps for testing your fuzzy-approach and maybe rename the maps for the testing to very simple names without any special characters (e.g. “test1”, “test2”). Maybe this already indicates where the error is located.
Otherwise you could also try to create a minimum test example with one of the standard locations (e.g. the GRASS North carlolina dataset) to see if the problem also occurs there (which might than be a problem with the module itsel). Such an minimum testing example can also be useful for other GRASS users to reproduce the error and help tracing the problem.
So overall, my tip is to simplify your fuzzy procedure stepwise to better identify your problem.

Best regards,
Johannes

No. I am not working in the PERMANENT mapset but I have some of my data in the PERMANENT mapset. I have tried with data stored in a different mapset, I have also to work in the PERMANENT mapset, I get the same error. I have also tried with mapsets (and datasets) coming with GRASS to check if the problem is my mapsets (or my datasets) but r.fuzzy.system returns the same error.

have you checked if there are any trailing spaces after your map name in the .map file?
Maybe you can post the .map file as it is and the result of g.list of your mapset.

The problem still persist. I did work in one mapset with all the input maps in this mapset, simple map names and only two input maps. The raster maps “B3/B4/B7” were imported by r.in.gdal and “ndii” is an index of these other maps computed by r.mapcalc. My .map file is similar to the one I sent to you with relevant input map names and fuzzy sets definitions.

These are the maps in my mapset:

g.list rast

raster files available in mapset :
B3 B4 B7 ndii

(Mon Jul 29 23:25:45 2013) Command finished (0 sec)

Error message from r.fuzzy.system:

Illegal filename. Character <

not allowed.

ERROR: Raster map <B4

not found

Same error message for a different input map

Illegal filename. Character <

not allowed.

ERROR: Raster map <ndii

not found

I am attaching very simplified .map and .rul files that use GRASS North Carolina dataset in the landsat mapset. I use file names as they are here but I tried with simple map names and got the same error message.

r.fuzzy.system maps=D:\Beatrice\GRASS\grassdata\nc_spm_08\landsat\Maps.map.txt rules=D:\Beatrice\GRASS\grassdata\nc_spm_08\landsat\Rules.rul.txt family=Zadeh imp=minimum res=100 output=test1

Illegal filename. Character <

not allowed.

ERROR: Raster map <lsat5_1987_40

not found

Thank you very much for your help,

Best regards,
Beatrice.

Hi,

thank you for the information. From a first view, I don’t see any major errors in you files.

However, to trace your problem I’d suggest to work only in one mapset and have all maps that are specified in the map-file in that mapset. Than you can also skip the trailing “@PERMANENT”. Furthermore I’d suggest to use only three or even only two maps for testing your fuzzy-approach and maybe rename the maps for the testing to very simple names without any special characters (e.g. “test1”, “test2”). Maybe this already indicates where the error is located.
Otherwise you could also try to create a minimum test example with one of the standard locations (e.g. the GRASS North carlolina dataset) to see if the problem also occurs there (which might than be a problem with the module itsel). Such an minimum testing example can also be useful for other GRASS users to reproduce the error and help tracing the problem.
So overall, my tip is to simplify your fuzzy procedure stepwise to better identify your problem.

Best regards,
Johannes

No. I am not working in the PERMANENT mapset but I have some of my data in the PERMANENT mapset. I have tried with data stored in a different mapset, I have also to work in the PERMANENT mapset, I get the same error. I have also tried with mapsets (and datasets) coming with GRASS to check if the problem is my mapsets (or my datasets) but r.fuzzy.system returns the same error.

Thank you.
Best regards,
Beatrice.

Hi Beatrice,

have you checked if there are any trailing spaces after your map name in the .map file?
Maybe you can post the .map file as it is and the result of g.list of your mapset.
Are you working in the PERMANENT mapset?

Best regards,
Johannes

Hi Beatrice,

perhaps you could contact Johannes Radinger
([hidden email]) for this, since he already used the module.
Please let me then know of manual improvements to be done.

Best
Markus

Hi,

I am experiencing a similar problem. I have followed the steps as in the
example, making sure all the maps are in the search path but r.fuzzy.system
keeps reporting an error regardless of the map specified:

My input map definition in the .map file:

%elevation
$nlow{left; -3,-2; linear; 0; 1}
$scar{both; -3,-2,0,2; linear; 0; 1}
$nhigh{right;0,2; linear; 0; 1}

Reported Error:

"Illegal filename. Character <

not allowed.
ERROR: Raster map
<elevation
not found"

I have also tried to specify the mapset using "@" as explained in
the example, still the same error regardless of the map (and respective
mapset)

My input map definition in the .map file:

%elevation@PERMANENT
$nlow{left; -3,-2; linear; 0; 1}
$scar{both; -3,-2,0,2; linear; 0; 1}
$nhigh{right;0,2; linear; 0; 1}

Reported Error:

"Illegal filename. Character <

not allowed.
ERROR: Raster map
<elevation@PERMANENT
not found"

I will be grateful for any advice in finding out the source of this error
and how to rectify it.

Beatrice.

I have also successfully tested r.fuzzy.system on GRASS 7.0. I think the
error with addons happens when using the menu option (Settings - Addons
extensions ....). Running g.extensions from the command console does not
report successful installation but provide a Traceback which in the end
reports

File "C:\Program Files (x86)\GRASS GIS 7.0.svn\Python27\lib\zipfile.py", line 807, in
_RealGetContents
    raise BadZipfile, "File is not a zip file"
zipfile.BadZipfile: File is not a zip file

Afterwards, the Addons of interest is/are available e.g when called from the
command console.

Please tell us when you downloaded winGRASS7 - there were significant wxGUI
changes recently. To get the version number:

g.version -g

I am now running a version which I downloaded yesterday, 19 Aug 2013, (g.version -g results shown below). I have checked, the GUI (Settings -> Addon extensions -> Install extensions from addons) still reports "unable to load extensions". The command line reports successful installation, atleast for the one Addon i have tested.
                                                     
g.version -g
version=7.0.svn
date=2013
revision=57466
build_date=2013-08-18

Beatrice.
