absolute save path of yarpdatadumper application

[jimingda]

The relative path of default application yarpdatadumper on yarpmanager is /data/head /data/leftArm ..... What is absolute path of save dumper data.

You can specify where yarpdatadumper will save the recorded data by means of the --dir command line option.
If the option --dir is not specified, then the name of the directory is made up based on the name of the portname.

Check out the documentation.

I mkdir and specify the absolute save path of yarpdatadumper on yarpmanager gui (both Module "Parameters" and Connection "to" item), launch the leftArm and rightArm and connect them, the status turned green. But neither data.log or info.log appeared on the path i specified.

Shall i modify the "host" item, but i found that the /From item is correct, or modify the node item directly on xml file from localhost to icub

Hi @jimingda

The parameter --name establishes the name of the YARP port, so please stick to this and don't use --name in the bizarre way I can spot in your screenshot above 😃

If you launch the following command from a terminal:

yarpdatadumper --name /log --dir test

Then, you'll find the logged quantities in files stored under the subdirectory ./test (relative tho the path from where you have run the command).

By contrast, if you launch yarpdatadumper from yarpmanager, files will be stored typically in the path from where you launched yarpmanager.

For example, if you launch yarpmanager from the directory Desktop as below, then you'll find all the relevant yarpdatadumper directories therein.

cd ~/Desktop
yarpmanager

Hope it helps.

Thanks. Because i launch the yarpmanager in terminal on path /home/icub, as specified in the pic, i found that i got the yarp dump data on path below:
/home/icub/home/icub/log/log20230629/leftArm/data.log.

And where can i find the tutorial of wholebody, except for https://robotology.github.io/robotology-documentation/doc/html/group__wholeBodyPlayer.html

We don't have a proper tutorial for wholeBodyPlayer.

However, you can read more about it at robotology/icub-main#654 and find the relative app available at https://github.com/robotology/icub-main/blob/master/app/wholeBodyPlayer/scripts/wholeBodyPlayer_App.xml.template.

Warning
Be careful of the section Pitfalls described at robotology/icub-main#654 that are mainly regarded with the name of the ports, which need to be fine-tuned.

Note
Since this thread is concluded, if you have further questions about wholeBodyPlayer, please open up a brand-new discussion.
