I am running a script in R that calls functions in grass from a iterative loop.
This works fine but every so often I get an assertion failure. This does not appear to be a function of the data I am sending to the grass executable. The assertion failure throws up a window allowing me to 'abort', 'retry' or 'ignore'. If i 'retry' it then asks me to close the program (the grass executable) and then the R script carries on as usual. i.e. the retry works and I will end up with all my data. The problem i have is that I wish to let this r script run over night but i cannot as I have to be there to supervise it, to 'retry' the commands. so my questions are: 1. Does any body have any idea why these assertion failures are occuring? 2. Does anybody have any idea how I might be able to catch these failures so that I can get R to retry the grass executable rather than myself. the error the grass executable throws is: "Assertion failed! Program: C\GRASS_64\bin\RCOST~1.EXE File:r:\pismere\athena\auth\krb5\scr\li..\g_initialize.c Line:76 Expression: (&(&g_mechListLock)->os)->is_locked==1" _______________________________________________ grass-stats mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/grass-stats
