If the interface is freezing, that means that GRASS is freezing (maybe it takes too long to process or the data is invalid). If you were passing wrong data, SEXTANTE would make a wrong call to GRASS and GRASS would produce nothing, which will cause SEXTANTE to fail afterwards showing an error message. But since it is not even finishing and producing the log info, I guess that womething wrong is happening with GRASS.
You can try to execute the GRASS call outside of SEXTANTE. In the SEXTANTE log you will find the commands. Execute them from GRASS and see what happens. The ParameterString is fine, but You can use ParameterFile as well, like this ParameterFile|pointsfile | GCP_Table |False False indicates that it is not a folder, but a file Regards, and thanks for you work 2012/5/10 skampus <stefano.cam...@regione.piemonte.it>: > I seem to have realized that you can put in each algorithm of Sextante all > the options originally planned for grass, by editing the specified command > file .txt which is (in my case) in C:\Users\ > skampus\.qgis\python\plugins\Sextante\grass\description > > So I did for the command v.transform, in order to perform the transformation > by means of GCP whose coordinates are into a separate table, as shown in the > help of command (http://grass.osgeo.org/gdp/html_grass64/v.transform.html). > > I opened the file v.transform.txt and i added the line ParameterString | > pointsfile | GCP_Table | > > v.transform > v.transform > Vector (v.*) > ParameterVector|input|input|-1|False > ParameterNumber|xshift|xshift|None|None|0.0 > ParameterNumber|yshift|yshift|None|None|0.0 > ParameterNumber|zshift|zshift|None|None|0.0 > ParameterNumber|xscale|xscale|None|None|1.0 > ParameterNumber|yscale|yscale|None|None|1.0 > ParameterNumber|zscale|zscale|None|None|1.0 > ParameterNumber|zrot|zrot|None|None|0.0 > ParameterString|pointsfile|GCP_Table| > OutputVector|output|output > > Once the command is launched by Sextante, i add the path to the table (using > both "/" and "\") but everything freezes and after several minutes it gives > an error indeterminate, not reported in the log Sextante. > > I'd like to know if the use of this external table relates to > "ParameterString" category or another not listed in > http://sextante.googlecode.com/svn/trunk/soft/bindings/qgis-plugin/src/sextante/grass/grass.txt > > thank you in advance > > -- > View this message in context: > http://osgeo-org.1560.n6.nabble.com/adding-options-to-sextante-grass-functions-tp4965610.html > Sent from the Quantum GIS - Developer mailing list archive at Nabble.com. > _______________________________________________ > Qgis-developer mailing list > Qgis-developer@lists.osgeo.org > http://lists.osgeo.org/mailman/listinfo/qgis-developer _______________________________________________ Qgis-developer mailing list Qgis-developer@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-developer
