0:00 - Introduction/Announcements

4:43 - I understand that ~150 participants participated in FitBit and EARS aspects of the study at baseline and 2-year followup. What are the future plans for further study? Is the goal for as many participants to provide these data as possible? Or will the sample stay around 150?

5:49 - Is it part of the protocol as kids come in for different visits to ask if their technology status has updated?

6:21 - It is unfortunate that the EARS app cannot be used with iphones. I know only 23% of the subjects in the pilot had Android phones. What percent of subjects in the full study are being tracked with the EARS app?

7:26 - Dr. Bagot mentions the cell phone (and Android versus IOS) prevalence in the population. Is there a ‘bias’ (economic, or other) due to who has a phone at all, and who is permitted to have a phone at that ‘young’ age?

9:27 - What about the spatial organization of where the participants are distributed equally across the different sites. Like is it kind of a uniform distribution or not?

10:48 - Yarik says reproman “Works nicely when everything is in datalad” Does that mean I must jump whole-hog into using data lad? (“Use or don’t use, there is no try”, I think I heard once). That seems like a high bar with a series of gotcha’s. Is there a way to wade in slowly?

12:23 - I probably should have asked this two weeks ago, but should people be using GIN (G-Node Infrastructure) with datalad? Does it add anything above and beyond using datalad alone?

14:51 - What considerations should I be aware of when using ReproMan (and the Repronim ecosystem more broadly) to manage small vs large datasets and locally acquired vs publicly available datasets? Is the ecosystem more suited for one use case over another?

19:08 - Thank you so much for the wonderful lectures! I am wondering how to differentiate the effects or changes due to development in the usage of social media or health-related measures, including sleep patterns and sedentary vs. active activity, from the changes due to Covid.

24:07 - If I understood correctly, for the Fitbit data ‘summary data’ is what is made available. Is there plans for the complete raw data, so that alternate summaries could be considered?

26:15 - I know participants’ activity is tracked with the FitBit Charge 2 but presumably newer devices are going to come out over the next few years. Is there a plan or timeline for providing new devices to participants? Will new devices be piloted first?

28:17 - Do you think the participant will increase their activity during the fitbit measurement period because they know their data is being collected?

30:07 - If I’m working with a new tool that comes in a singularity container, is there a recommended way to interact with the container to debug/understand how I should build the command I eventually want to run on my datalad dataset?

33:00 - Can just anyone add any old container to ReproNim/containers? Is there a search/discovery on existing containers? I just want one with FreeSurfer 9.2, can I just reuse one that’s already there?

36:10 - Both Dr. Bagot’s lecture and in her paper mention “geolocation” using the GPS on subjects’ smartphones but these data are not discussed in any more detail. Can you elaborate on what geolocation data are (or will be) available? 

37:30 -  Have you used the fitness/screen/media data collected to research anything related to the pandemic?

43:49 - How do you choose which Apps to ask kids how much time they are spending on them?

44:50 - Regarding the previous question, I wonder if we can compare the days when children went to school with the days or the period when they didn't (due to the school shutdown, etc). 

47:25 - Is there an “ask YODA” resource covering frequently asked questions?
