I'm afraid that in the current distribution there isn't any way of doing this except for FSL-VBM which indirectly measures changes in the grey matter structures bordering the ventricles. However, a change in ventricle size would be expected to arise from a change in other structures, so this is quite informative.

Hi;

Thanks! Is there any other way to perform vertex analysis of Lateral Ventricles using FSL? I'm kind of stuck here :)

All the best

Hi,

I'm afraid there is no easy way to use FIRST with any other segmentations at present.

All the best,
Mark

The common way to do this is to use FIRST for segmentation but because FIRST doesn't segment ventricles i used a Harward-Oxford Atlas to make ventricle mask for each subject and use it as a mask in FAST output of CSF. Is there anyway can i use these NIFTI files without .bvars files in Vertex Analysis?
