Thanks for clearing that up

I have made v.net.centrality run in QGIS 2.18 without any problems - even
though the setup is a little different in 2.18 as you do not need to provide
a point layer and you unfortunately cannot add costs on the network.

According to https://gis.stackexchange.com/a/309445 this warning is
raised by default it seems.

So, no ideas where your problem comes from. Over here the function works
and produces a result.

Re: [QGIS-Developer] v.net.centrality: Sorry, is not a valid parameter

2019-10-31 Thread Bernd Vogelgesang 

I have no idea what this function does, but when trying with your data
on 3.10 on Linux without any default parameter changes, it first
complains about a wrong output type, because in the advanced parameters,
there is no output type selected by default. Switching this to auto
gives a resulting point layer.

Cheers,
Bernd
