Is there a way to concatenate GRT "demo" files so that I can get an entire flight in one file on SavvyAnalysis?

Thanks!

Thanks Bro, you made my morning. That one was gonna haunt me.

If it is I haven't found a way to do it.

Concatenated.... .. Amazing what we learn on this Forum.

You guys are funny.

Concatenate is used in computers often.

Walkman, have you tried to 'cat >> file' them together? I haven't tested it but it's just a binary file. You may have to strip some headers but in theory it should work.

Oh, I get it. I remember my dad used to eat a lot of prunes when he got concatenated. I know those computer geeks get crappy tunnel syndrome so it just follows that concatenation would follow. Thanks for clarifying it for me Sid.

That reminds me of a pic I took a few weeks ago...

Now that's a good way to start a Wednesday!

I don't know about concatenating files, but I'll ask Jeff tonight when he gets here. I think he dreams in binary.

Here's another option. If you're planning to record a flight specifically for uploading to SavvyAnalysis, you can set your EFIS up to record up to 120 minutes of continuous flight. It uses about 1 MB/minute, so make sure the Max File Size is also set to a number large enough to record the flight and you have enough room on your USB memory stick.

Cool stuff there, thanks for the link

And, kudos to whoever wrote the "feature of the week"---------nice to see something that a nontechnogeek can read/understand.

I know HOW to do it, but not whether it will work or not, and didn't have any files to test on.

Actually, even if it will work, you have to be careful about getting them in the correct order.

cat `ls -tr DEMO-<day>-<time>*` > DEMO-<day>-<time>-ALL.LOG

should work

lol after the arkansas moonshine this weekend, my pipes (*nix reference) are redirected to /dev/null

The longest amount of time I can get it to record in a single file is 18 minutes. What am I doing wrong?

 

[RV8iator]

Katie will have to verify this, but the way I read it is that you can specify a file size and a max recording time. The file size will control this and 15MB is the largest selectable now. This size for me equates to slightly less than 15 minutes of recording time in each file.

If you're recording less data then the time can be up to 120 minutes.

Sorry, Widget is right. This morning I went to my demo units and I checked the max time setting on the EFIS, but did not check the max file size, which is just 15 MB. The EFIS records so much information these days, it won't go the full 120 min.

So now I'm really interested in how to concoct/constipate/connect the demo files.

So, you've got two hours of flight data in 15 MB (i.e. 15 minute) chunks?

That's just 8 files to put together. You should be able to decode the binary demo files using the decode to spreadsheet program on the GRT website, then paste them together in notepad (or ideally with notepad++) (deleting the headers out of all but the first file).

Thanks Mike, I really appreciate that! That was me, GRT's resident "average homebuilder." My flying experience with the Sport and a lack of prior knowledge about electronics have made it easy for me to step back and ask real-user questions. Over the past year I've developed a real love for translating Technogeek into English.

Savvyanalysis has a fairly low max file size anyway. I cat'd all my DEMO files for a 2 hour flight into one and then attempted to upload. Its more than twice the max size. So, issue might be moot.
