Read QSM created with Simple Forest #4

Closed GiulioDonatiSarti closed 2 years ago

Hi Olivier, first of all I would like to thank you for your work; it is really interesting!

However, at the moment, I have some problems working with it....

I have obtained a QSM from a TLS point cloud with the SimpleForest plug-in in CompuTree. Now I would like to use your package to extract some information from the QSM, but I am not able to read the .csv file and build an object of class aRchi. In fact, when I run the build_aRchi() command I get the following message: Paths is empty Point cloud: 49130 points Node table is empty No operation realized

Any idea where I might be going wrong?

Thank you very much in advance, Giulio

For completeness I attach: (i) the .csv file of the QSM obtained from SimpleForest, (ii) the .txt file related to the point cloud and (iii) a copy of the code I am trying to use.

I just renamed two columns of the .csv and all works.

Specifically, I changed the name of: branchID > BranchID; branchOrder > BranchOrder.

Hi Giulio, Sorry for the late reply. I did not see it... Great that you managed to read you QSM. Thanks for reporting the bug. I'll correct it in the next version (2.0.0). Very soon.

Olivier

Now V 2.1.0 makes possible generating QSMs.

Thanks @Blecigne !
