Hello Denis, Thanks for your answer. I want to build a module that allows me to pick sulci in a graph (in a 3D window) and add them in a new graph. Ultimately I want to merge all the buckets from the selected sulci, if they are connected, and re-mesh the result. The aim is to be able to merge a sulc...

Hello Denis, I am back on this post to ask you a few more questions. The wrapper you are talking about for objects like vertices is, I assume, AGraphObject. Am I right ? As far as I understand (not much, so far), I can get a AObject selected with the mouse, then cast it to a AGraphObject. If the cas...

Salut Denis, There's no good reason for it not to be in the core (I guess Renaud just dared not add it in the core), but we can move it if you need. I will need to get the buckets from all the sulci selected to remesh them, so yes please, the AddNodeCommand command sounds like what I need. Olivier

Hello, I would like to add a vertex to an object AGraph *ag I thought I could use ag->attributed() but it does not have an addVertex() method. Maybe I have to cast it to a Graph type to apply the addVertex() method. Or can I use ag->Graph() directly ? In this case I am not sure the vertex will be re...

Thanks Denis, The index attribute is unique in a graph, it is assigned upon creation (by the Vip library) to each node, but in different graphs, the same index has no common meaning. this is OK for me. I want to do all this at an individual level, not as a generic (i.e. subject independent) process....

Hi there, I would like to extract several bits of sulci from an individual graph. More precisely, I would like to select a few nodes in the graph, that fall under the same label. For instance, nodes having the label S.C._left. My problem is that I don't want ALL the nodes labelled S.C._left but just...

I installed a new version of Python (2.4) and compilation of cartobase seems to be OK.
Thanks a lot Yann !

Thanks a lot Yann. I just got the install directory, I will have a look at that.

Hello everybody, we are still trying to compile the sources on a Debian distribution (without being root). We managed to install libsigc++ and libxml2 that were necessary. We then tried : build-config --buildMode release --build --verbose --version main cartobase Apparently all necessary libraries a...

Hello Yann, Denis is an example of very good specialist Indeed ! Actually we solved our problem, the file copy from my machine to gregory's missed some files, for some reason, and thoses files were apparently necessary for build-config to identify cartobase. Something like that :? Sorry everybody fo...

Hi Denis, we tried specifying the version as you said, with : build-config --buildMode release --build --version main cartobase and we get the same error message. There's no other version of the code in our source directory so I guess that means that build-config thinks there is no source code at al...

Hello Denis, I am taking over this conversation to give you more details about the compilation. Grégory and I have been trying to install anatomist on a Debian machine, because that's all we have here for students. And we don't have any root access so it's not gonna be easy . We just want to have an...

Thanks Denis. Trick: in Anatomist, there is a recognition module which performs the relaxation with a colored 3D display while it runs. The configuration panel for it shows a (quite) complete set of options and basic help on tooltips. To use it, load in Anatomist both a data graph and a model graph,...

Hi Denis, it's nice to have you back ! I sort of optimized the "one large clique" version but it still is far too slow to handle real data. So I will try now the "many small cliques" version. Their number should be way below n^2 since each node sees only a small number of other n...

Hello there, I'm adding one more question for when Denis comes back from holidays :wink: When building cliques for a labelling process I have sometimes two choices. Let's say I am building a clique for a "datadriven" potential function. The potential of the clique is the sum of the potenti...
