PC-based analysis package for exported data?
PC-based analysis package for exported data?

Jeff, I love the app.

While real-time relative speed and relative laptimes might be cool for the car guys, us bike guys either have the phone on the tailsection, or inside our leathers.

I do a bunch of analysis in the pits when I'm learning a track, or making some setup changes (temperature, second-choice tires, etc). While this might be useful inside the app inside the phone display (I kind of think it's a design tenet of yours to do everything in Android environment, which is laudable), I can email the .xls to myself and then work with it some in the pits between sessions or races.

(Which reminds me - is there a good utility to pull Trackmaster files from the filesystem via USB rather than email? Motorola Media Connect can't see 'em and I don't have a filesystem manager that seems to let me actually move the files between directories).

Anyway, one of the more useful utilities I've used in the past had the ability to plot speed vs lap distance for each lap (find a lap based on the first split, I guess) and then plot it, like this:



In this file (Inde Motorsports Ranch, Willcox, AZ, last Saturday), you can see 1Hz sample error galore (I've ordered a QStarz 890...). But it's really useful for me to compare lines/corner entry for the fastest way through a combination, etc; it's even more useful with acceleration data, and best when I compare my session with a faster racer's data.

Do you (or anyone) know of a utility I can use with the .xls (or csv) data for pc-based analysis? Doing the above in Excel was a major pain, and I would rather not automate it if there's something free or freely available...

Thanks,


dave

The easy question: Yes, you should be able to move Trackmaster files from your phone easily via USB. I'm not familiar with the Motorola Media Connect. But when you connect your phone, your Notifications bar should show a 'USB Connected - Select to copy to/from your computer'. Click on that and your phone will appear as an external drive on your PC. You can drag and drop files. Trackmaster files will be in the Trackmaster folder.

Now for the analysis question. Currently, Google Earth, MS Excel, and Google Docs are the only PC-based application available that I use for analysis. The important word there is currently. I am working on some cool new non-android features for data syncing, searching, and analysis. I don't really want to say too much at this point, but it will do what you're asking for.

I know that Motec offers their software as freeware, but it won't read generic .csv files. It's got a proprietary format, but I know nothing about the actual file structure. But, I know that Motec i2 Pro is AMAZING for reviewing data. I use it for sim racing all the time.

If there were a way to easily parse the Trackmaster logs to an acceptable Motec i2 format, that would be wonderful.

Just saw this and wanted to second that emotion. I've used the Motec software with GTR in the past and it's amazing. If we could export to that format that'd be great, but I'm curious to see what's coming regardless.
