betweeness clustering coefficient

[LAOUAR]

Hi everyone, Please, i ve issues with VGA, i want to get : control controllability and clustering coeficient, betweeness. 1.i ve set a grid (20) 2.tool-visibility-make visibility graph 3.run visibility graph analysis 4.calculate visibility relationship; i selected both of - include global and- local measures,- i put radius n. But unfortunately i didnt get any one of the abovementioned measures except visual integration. (i ve used depthmapx the latest version in github.) Please could any one answer me. Thank you.

Have you tried turning off simple mode in the settings menu?

Thank you very much Christian Sailor, it works now, i am really very grateful for that. Please i ve another question about betweenness how can i calculate it or get it in VGA. Thank you have a good day.

Betweenness is not calculated for VGA (it doesn't make much sense) in depthmapX. You best bet is to export the VGA connections and calculate it yourself in a different app, or in python using a dedicated library.

Thank you very much Petros Koutsolampros for your answer, it's really kinfd from you. However, i am not very familiar with python, can you give me more informations about how can i calculate it from vga connections, because i am working in GIS file and i want a grid map of betwenness so i can join it with other parameters of my study. Thank you in advance.

[pklampros]

@LAOUAR this is a particularly broad question.... In short, you export the VGA connections from depthmapX, import them into Python to make a graph (perhaps with the igraph library?), and then calculate Betweenness using the same graph library.

[LAOUAR]

Is it possible in R? Thank you very much

[pklampros]

It certainly is, look at igraph for r, and betweenness using igraph in R

[LAOUAR]

@pklampros thanks a lot, i am so grateful.

Hi @pklampros , please in which format can i import VGA to Igraph R? Thank you very much. Best Regards, Dounia Laouar
