Hi, should be 'map' in v.edit (for GRASS7) replaced by 'input/output'? When options are specified incorrectly or the module crashes, vector is not backuped, data are lost. The input/output paramaters would be probably better for this module. What do you think? Martin -- Martin Landa <landa.martin gmail.com> * http://gama.fsv.cvut.cz/~landa
