How to correct sulci labels otained by automatic recognition

[ericj]

Hi all,

I'm experiencing some issues with the automated method for sulci recognition. It is far from being huge errors, but it would be better if I could correct some bad recognized sulci. I've quickly looked into BV to find a special routine which I didn't. Is there any simple way to manually correct sulci labels in BV or Anatomist ?

Kind regard,

Hi Eric,

Yes you can do it manually.
Here an extract of the next tutorial:

Code: Select all

Load a graph.
Place it into a browser.
Select a node.
Right-clicking => Modify name.
Give a new value.
Place your cursor on the graph object (left panel).
Right-clicking => File => Save.
Give a new name if you don't want erase the original file.

You must know that in the case of sulci graph, there are 2 attributes to label a node:
'label' attribute : used by the brainvisa process.
'name' attribute : set to 'unknown'

I advise you to keep the 'label' and to fill in the 'name'.

Editing graph labels is explained in Anatomist's documentation.
Contrary to the previous comment, I advise you to modify
the label, otherwise you cannot do morphometry with
standard brainVISA. If you want to modify the name attribute,
you should copy labels in names before using a
commandline AimsFileConvert with options described
elsewhere in the forum I guess (I will stop here, I am in hollydays).
