Smaller number of iterations run without any problems. I was able to reproduce the error by using r.thin on the elevation.dem from the Spearfish data set. The following error is printed to the console. {{{ Exception in thread Thread-25: Traceback (most recent call last): File ""C:\OSGEO4~1\apps\Python27\lib\threading.py"", line 808, in __bootstrap_inner self.run() File ""C:\OSGEO4~1\apps\grass\grass-7.4.0\gui\wxpython\core \gconsole.py"", line 156, in run self.resultQ.put((requestId, self.requestCmd.run())) File ""C:\OSGEO4~1\apps\grass\grass-7.4.0\gui\wxpython\core \gcmd.py"", line 614, in run self._redirect_stream() File ""C:\OSGEO4~1\apps\grass\grass-7.4.0\gui\wxpython\core \gcmd.py"", line 643, in _redirect_stream self.stderr.write(line) File ""C:\OSGEO4~1\apps\grass\grass-7.4.0\gui\wxpython\core \gconsole.py"", line 300, in write self.message += line.split(':', 1)[1].strip() + '\n' IndexError: list index out of range }}} Any Ideas what might be going wrong?
