I am trying to run fv3jedi\_parameters.x using the bumpparameters\_nicas\_gfs\_aero.yaml. I’ve added in the section for computing and writing out stddev, and it runs until starting to write out the nicas files. I get the error message:

!!! ABORT in nicas\_blk\_compute\_sampling\_c1 on task #0001: no valid level

I’m assuming that there is perhaps something missing from my yaml file. I’ve attached it here:

I’ve resolved this issue. But have encountered a new error that I have not seen before. During iterations - this error occurred.

!!! ABORT in stripack\_trmesh on task #0009: N \< 3  
Traceback for instance 11 :

I was able to avoid the above ABORT by reducing the number of iterations in BUMP. I’m working on “load\_var” in hyb-3dvar\_gfs\_aero.yaml. It would be helpful to see a complete yaml file that includes this.
