I'm using a Ubuntu Virtual Machine with minicoda 3

Hi @mikeyJ-1999. Thanks for filing an issue. This looks like a memory issue. How much memory do you have available on your VM?
Your inputs are relatively large, and assuming float32 or float64, will require a lot of RAM for in-memory warping. Depending on VM OS config, there may also be some monitoring that kills processes occupying lots of RAM.

Hi

Thank you for the reply

I'm current allocating 10gb of ram to the virtual machine and allocated 250gb of storage. When I try to run the terminal now it closes without giving any errors

[dshean]

OK. 10 GB is not much for uncompressed in-memory storage of your large rasters, but maybe OK swapping to disk.

Just to confirm "closes without giving any errors" means that the script successfully ran to completion, or that it prematurely exits without throwing an error?

[mikeyJ-1999]

Sorry for the cofusion. It closes without giving any errors.
