Hi Rodrigo,
Sorry about the confusion due to this issue - after diagnosing the problem, a bug was identified and fixed in filtering the earthquake rupture distance. Attached below please find the FetchOpenSHA.py script (also in a recent commit -
https://github.com/NHERI-SimCenter/SimCenterBackendApplications/pull/94/commits/f27b02c5b992ea0c4912e9dd62b855c149019bbd) and the output IMs folder of the test (99 realizations of PGA for each site in the SiteList.csv).
This is going to be updated into the next release, but in the meantime, a quick patch for this issue on your local is: please download the attached python script and paste it into the directory under the R2D application (i.e., "R2D_Windows_Download/applications/performRegionalEventSimulation/regionalGroundMotion"). Please test and feel free to get me back. Sorry again about this inconvenience and thank you so much for identifying and reporting this problem to us!
