[caret-users] CerebralHull.vtk broken?

[John Harwell]

Michael,

The problem is that the VTK file has commas instead of periods for the  
decimal points.

POINTS 13962 float
43,4298 -2,86038 -43,2584 41,6454 -2,83801 -43,5191 41,5233 -1,39223

42,4223 -0,286592 -43,9258 41,397 -4,53123 -42,7291 43,2797 -6,69071  
-41,6795
44,6393 -4,59945 -41,6029 41,1897 0,785529 -43,19 44,8851 -0,354329  
-43,4192

If I replace the commas with periods, Caret, using the VTK library, is  
able to read the file successfully.

The use of commas, instead of periods, is caused by a locale  
(internationalization) set by either VTK or the C++ compiler used to  
compile VTK.  Since you built the Debian version of Caret, you will  
have determine the source of the problem.
