Hi Laura,
The “could not create source file” could be from any number of things, from running out of disk space to running low on memory to not having write permissions.
However, I don’t recall seeing the "warning:FileSetFileOption: invalid file or format” error before with regard to regridding, so I can’t be sure what this means.
It would help if you could provide the full script and data so we can run it. See our ftp for a place to upload the files:

Thanks,
