Hi all,
I’m new with GRASS GIS and I’m interesting to learn the use of r.fuzzy.* tools. I read Jasiewicz paper (A new Grass GIS fuzzy inference system for massive data analys) and I run r.fuzzy.system tool without error. Now I’m trying to understand the process step by step using r.fuzzy.set and r.fuzzy.logic. I produced membership raster with r.fuzzy.set but when I use its outputs to run r.fuzzy.logic I have the follow error: ERROR: accum_abs_high_memb@PERMANENT is not of type CELL.
The tool requires two input raster data and both are FCELL. I have no idea where can be the error, both input data are from r.fuzzy.set.
I’m running Grass GIS 7.2.1 in Window 10 and I’m using spearfish60_grass7 maps.
Thanks in advance.

AFAICT, the message about CELL was an typo (should be FCELL), and one of the FCELL types was ignored and the module fataled out in any case. Shows that you are probably the first one to use these modules in a long time...
I've tried to correct according to my understanding after a rapid reading of the code. Could you reinstall the module with g.extension and tell us if the error has been corrected ?

Sorry, just saw that you are on Windows: you will have to wait for the module to be recompiled to get the changes. The latest tomorrow...

Thank you Moritz,
I installed OsgeoLive virtual box with GRASS to run fuzzy tools also with Linux, so I’ll run r.fuzzy.logic there and I’ll tell you if it works.
