Suppose you want to run the FP Temperature prediction model outside of an official LR run. One way is to run LR in TEST MODE. This will run all the Thermal models and store the results in the test directory you have specified.

But if you want to run the FP model only, then you take the following steps.

BACKGROUND:
When you run LR, it eventually works its way down to the Thermal code and types out this message:

Running the thermal code...

Then it runs "run_models.pl", supplying it with the Current Load and the computer Host Name. run_models.pl, in turn, will set up the Ska environment for you, accepts the directory you specified for output, and run all the models.

So if you ever want to see how LR runs the models, first look at run_models.pl in the LoadReviews/script subdirectory. Be aware that directories and current load specifiers (e.g. AUG0414A etc) are handed down from LR to "run_models.pl", and thence to the model itself.

But maybe you want to run a specific model directly. The following are the steps necessary to run the FP model; running the other models is similar althiough they live in a different directory. Here are the steps involved for the FP model:



• Open a new window.


• CD to whatever location to which you want the output directories to be written.


• The first thing to understand is that the model relies heavily on the Ska database, so the next step is to run the setup in your window in order to access the db:
  
  source /proj/sot/ska/bin/ska_envs.csh



• Run the model. The following command example is split into separate lines to make the inputs clear. You will do this on all one line or use line continuation:
  
  /proj/sot/ska/bin/python /data/acis/LoadReviews/script/fp_temp_predictor/acisfp_check.py
  --oflsdir=/data/acis/LoadReviews/2014/JUL2814/ofls
  --outdir=./out_fptemp
  --model-spec=/data/acis/LoadReviews/script/fp_temp_predictor/acisfp_spec.json
  --verbose=1


You need to know what load you want to run the model against. "outdir" can be any name you want for the output file directory. The verbose flag allows you to get varying amounts of feedback. Your choices are 0,1, and 2.
