@yunjunz I could use your help uploading the new sample data to the correct place on Zenodo.

Hi @forrestfwilliams, I added you to the creator and contributor list on the previous Zenodo page. Could you try to see if you could update a new version?

If not, I am happy to test and upload the version. Let me know please.

Looks like I have a couple of Zenodo profiles. Could you make sure the username ForrestWilliams is a contributor?

[yunjunz]

I added you connected with this ORCID number, which I believe is correct.

After more reading, it seems that sharing the writing permission of a single repo with another user is not possible on Zenodo yet (zenodo/zenodo#151). So I will go ahead and upload it tonight.

The new dataset runs through #1180 without issue. However, this dataset missed the lower half of the data, as shown below. Maybe you want to recreate a new one that covers the entire EQ? BTW, the previous example dataset uses desc track 71, while this one uses asc track 64, which is totally fine if there is no data gap issue.

[forrestfwilliams]

@yunjunz shoot you're right, sorry! I'll get you a new version based on desc track 71.

@yunjunz here is a link to a descending 71 track version of the data.

The main smallbaselineApp run works great, but I noticed that there is an issue running smallbaselineApp.py --plot at the end of processing that I haven't seen before. Running the sub-command:

view.py --dpi 150 --noverbose --nodisplay --update --memory 4.0 numInvIfgram.h5 --mask no

Results in an error within the matplotlib axis tick functionality:

  File "lib/python3.11/site-packages/matplotlib/ticker.py", line 799, in _set_format
    loc_range_oom = int(math.floor(math.log10(loc_range)))
                        ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
ValueError: cannot convert float NaN to integer

Have you come across this one before?

For now, I've disabled plotting in the configuration document, so we don't encounter the error when running the standard smallbaselineApp.py, but we may want to circle back to this at some point.

Thank you @forrestfwilliams for the update. I have uploaded the dataset to Zenodo (https://zenodo.org/records/11049257), an ERA5.h5 file is also attached within the tar ball, to simplify the test / running for the first-time user.

I am able to re-produce the error you have. If I turn off the NO_DATA_VALUE handling, the plot went back to normal. But I could not really locate the cause of this behavior. Thus, I turned off the plotting during the testing for now, and let's fix it afterward.
