Hello,
I have what looks like a simple question but don't seem to be able to find an answer. We got some brains with sulci that have been manually labeled by a collaborator. SO all the 'name' attributes are filled in the fold graphs. This has been done directly on the unlabelled graphs (L/Rsubject.arg). We need to use them in a process that expect a labelled graph. How do we indicate to the database that these graphs are actually manually labeled ?
We think we have to change the attribute manually_labelled from the value 'No' to 'Yes' but don't know how to do it.
Thank you in advance for your help.

Re: Manual labeling of sulci
Hi Olivier,
From the brainvisa database point of view, database attributes are driven by the files paths and named, so it is just a matter of the sulci graph location. From the processing tools point of view, it's not so clear: some of them are able to use a "label_property" attribute in the graph which can indicate "label" or "name", but some tools need to be specified which attribute should be used for labels by commandline options or function parameters.
Anyway there in brainvisa you can

Anyway there in brainvisa you can
- import a sulcal graph using the "import graph" process (in data management/import), or the higher-level "general import" process (make sure to select the data type as, for instance, Labelled Cortical Folds Graph, before clicking the red database icon)
- switch between manual or automatic labeling modes, using the process "Sulci switch manual labels" in Morphologist/sulci/recognition. This one will copy the graph at the appropriate location.

Re: Manual labeling of sulci
Thanks a lot Denis, problem solved. Our process can handle both names and labels but was looking for a labeled graph. The solution was the import with specifying manual labelling.
