Hi Dinesh,
presumably nothing went wrong...
In the new version of TBSS, FA and skeletonised images are masked by the *intersection* of all your FA images. In other words, this new pre-processing prevents you from doing statistical analysis with some data missing. If some parts of the brain are missing in your study, it means that at least one of your images does not contain these parts of the brain.
If this is only one suject that reduces considerably the spatial extent of your analysis, then you should probably remove it from your study.
Hope this helps,
Gwenaëlle
