Today was day two of the GENETIS hackathon. See the previous entry for details on day one.

I continued working on the XF scripting for the PUEO horn antenna. Amy showed me an actual horn antenna from ANITA in Lisa's office so I could get the dimensions and see how the loads (power sources in XF) were offset. Offsetting the power sources led to fixing the asyemmtry problem from yesterday. I tested offsetting the loads by various heights and found that they all give the same gain patterns except for when they overlap, proving that they were interfering with each other when they crossed.

There is still, however, an asymmetry between the x and y axes (but the gain patterns are now symmetric across either of them). This is more reasonable, though I'm not positive that it should be this way. I attached an image of the gain pattern to show this asymmetry. Note that it is still at 83 MHz, which is well outside the PUEO bandwidth, but higher frequency gain patterns show the same thing (but they have more nodes so they're harder to look at). I attached images from the x-axis, y-axis, and above of the gain pattern. One way to check this will be to compare to the data stored in PUEOsim/icemc and see if they demonstrate similar asymmetries.

My next step is to test the constraints we've decided on using the script. I'll try out a few different values of the parameters and then if everything is working I'll use the GA Ryan and Dylan wrote to generate many individuals and have XF make the models for them. We don't necessarily need to see the simulation outputs from those XF runs, we just need to see if we run into error. Beyond that, we need to figure out how to extract the proper gain data from XF to create the same format that PUEOsim and icemc use. 

Amy also mentioned that we should add the opening angle of the horn antenna as a gene. This may be a little tricky but should be doable. Once we are set with the current XF script and changing the data formatting to match what PUEOsim and icemc need, I'll work on adding that as a gene.

Dylan and Jacob

We tried to get IceMC running and able to read in gain files -  we failed. Something was wrong with my make files and Jacob’s c++ compiler, so neither of us got a working version of IceMC. We then switched gears to focus on pueoSim. I created a branch on the nicemc github to output a veff.txt in the format of IceMC, so we can reuse the already-made code. Jacob and I also have been trying to install pueoSim, but we’ve been running into many errors and issues from the “C++ Gods”. For the next steps, I will finish the veffective branch and create a pull request. Then, I will work on a branch to make it so pueoSim can read in a variable path  to the gain files.

Tuesday: Created a new branch on the PEUO repository, version0.0,  and placed the repository in the same location as the Ara one for familiarity. I also added an alias to this directory onto the genstudents channel if people would like to add the path to their .bashrc's. I then went through the the Evolutionary_Loop directory and cleaned up any residual Ara based files that were not needed to run this loop. This will make navigating and troubleshooting easier as we finish building. This branch was then commited and pushed to the github and submitted a pull request.
