I am trying to run a watershed segmentation using the SAGA plugin in QGIS. Unfortunately, every time I have tried to run this on a specific file QGIS freezes. The log output reports the following:
What is particularly odd about this is that it worked on a similar file just a few hours prior. The only difference is that the image it keeps failing on is a DSM generated by BCAL lidar tools and the image that was successful was a DSM generated by ENVI lidar.
I also ran the watershed segmentation using the standalone SAGA on the file that kept failing and it was completed successfully.
