Hi,
Some background:
We are creating ODK forms (for the first time!) for data collection in Kenya. Our plan is to have data collected on Samsung tablets during the day. Each night the data will then be transferred to a laptop. We would like to then have those files zipped and sent via LeapFile to an analyst in the US once or twice a week. The analyst will then use Aggregate or Briefcase to see/analyze the data.
Concerns:
-
My first concern is that our office in Kenya wants to be sure that the tablets and ODK will sync with their laptops. I'm still waiting to find out the specs of their laptops, but are there certain requirements that the laptops need to have in order to capture and store the data?
-
And are there things I need to be concerned about when using LeapFile to transfer the data? I'm assuming this is possible to do!
-
Do you have any suggestions on how to determine if Aggregate or Briefcase is a better option for pooling data for analysis?
Any and all help is much appreciated!
RE: (1) the key requirement is a USB port and cable to connect the tablet
to the PC.
The nightly procedure would be:
(1) make sure that all saved forms are completed (there are no incomplete
forms showing on the 'Edit Saved Forms' screen).
(2) Power off then power back on your tablet
(3) connect with USB cable to laptop
(4) copy the 'odk' directory from the tablet to the laptop
(5) disconnect USB cable
(6) Use the ODK Collect 'Delete Saved Form' screen to delete all the saved
(filled-in) forms on the tablet.
The power cycling in step (2) seems to correct several problems relating to
the USB connection in steps 3-5.
If the field office does not need to do anything with the data, it can then
zip up the odk directory and send it onward. Otherwise, it can use ODK
Briefcase to process that directory and export a CSV for analysis.
*RE: (3) *
ODK Briefcase can be used to read all the data in from the zipped/extracted
odk directories sent from the field office. If your form has repeat
groups, ODK Briefcase has better Export to CSV capabilities than ODK
Aggregate.
The only advantage of ODK Aggregate is if you want to publish or import
data into Google Spreadsheet, Fusion Tables, or some other service, or if
you want to set up your own MySQL or PostgreSQL database for analysis --
using ODK Aggregate on your own server can simplify that process, as it
parses and inserts the data into traditional relational database tables.
···
--------------
As always, you should try out any workflow before 'going live' to make sure
that things flow smoothly.

Thank you, Mitch. This is helpful. I will certainly give it a try.
And, apologies for the repeat post - didn't know the first had gone
through.

I'm doing some test runs and I don't see the 'directory' you mention. When
I connect the USB to my PC, I see a folder called 'odk'. Inside that are
three additional folders. I imagine the one that says 'instances' is the
one I need (I need the one with the finalized data/forms) - or do I need
data collectors to copy the entire 'odk' folder to the PC for zipping and
sending on?
Also, we are collecting gps and audio material. When I open the 'instances'
folder, I can click on the audio file, but my PC isn't able to play it for
me. Is this because I still haven't downloaded briefcase or am I doing
something else wrong?
Thanks!

Sorry -- 'folder' and 'directory' mean the same thing.
You need to copy the entire 'odk' folder to your laptop and send it on.
The audio format is in .3gp (or .3gpp). These are playable by Windows Media
Player. You may need to update your system or download and install the
latest version of that app
