It is landsat 8, which is 16 bit. So that may account for one issue. If so, the error about matplotlib is a 2nd issue.

Also, it doesn’t seem to work otherwise. I can mark training fields with no problem. I can export them with no problem. But when I click the update button, the preview screen goes blank for a bit for each class then returns to the original base raster with nothing showing. The command console displays the following errors (one for each class): Data error preparing signatures: value (19592) > num of cats (256) Data error preparing signatures: value (8089) > num of cats (256) Data error preparing signatures: value (11048) > num of cats (256) Data error preparing signatures: value (9218) > num of cats (256) I’ve looked at the very slim help file and it did not help. Copying Helena and Anna in case they’ve be successful with this working. Michael ____________________ C.

It says it was unable to import matplotlib. Then it says it did find matplotlib but it was the wrong architecture. If I fire up Python from the GRASS terminal and import matplotlib, it is fine. I also tried to install matplotlib from the terminal in case it would find a correct architecture version. This also went fine. So I begin to suspect that this is a bug instead of a problem with my systems. Any thoughts? Mac OS X 10.10.3 GRASS 7.0.2, compliled a week ago. Michael <error.png> ____________________ C.
