Processing raw Spectre Monte Carlo data ?

MarkGr15

I am using OceanXL (within ADEXL created scripts) to kick off Monte Carlo simulations. I would like to be able to post process the data myself, to be able to calculate the mean, sigmas etc... 

Is the raw data available for this, and how is it organized? I am having a hard time deciphering the file structure etc....

I do see the results listed in an output log, when I add " -log ocean_montecarlo_output.log" as a an option to the command line that I use to kick off my scripts.

The upshot is I want to be able to find the raw data in the output directory, and post process the measured data.

I am using IC6.1.6-64b.500.9.  

spectre -W  => sub-version  13.1.1.049

thanks

    Hi Mark,

    You are right, I did not understand your question as it was not clear to me you were looking only for the results of its measurements - not the raw data. Dumb question on my behalf, but is there a reason you cannot just take the data from the ADE-XL results data as a comma-separated file? You can access the data directly without having to access the results. If you are using IC6.1.6.500.9 or later, you can use the procedure described in Solution ID 20309689.

    Irrespective of that comment though, unlike when running Monte-Carlo prior to ADE-XL, I have not found the results of the measurements saved in a file as it was in IC 5.41 in the results directory.

    I often just run an ocean script, pull out the data and recompute it to get the statistics. I find this easier than creating a new expression and re-evaluating the data from a run. This assumes, of course, that you have checked the option to save the data for all the runs!

    My apologies for not understanding your question Mark,
